How is it possible for a steel anvil, which is mainly made of iron, to float in the fluid? Everything depends on the density of the object and the density of the liquid. The density of iron in the solid state is 7 874 kg / m3, whereas the density of the liquid (mercury) is 13 534 kg / m3. It tells us that iron is about 40% lighter at the same volume, so it's easy to swim in mercury, because the greater the gravitational force affects the mercury. . . 📢 Tag a friends to share knowledge... . ⏰ Turn on post notification and follow for brighter future… Follow me @undercover_engineering . #anvil #mercury #mystery #density #floating #knowledgeispower #learn #engineer #engineering #follow #folowme #school #instaschool #teaching #intelligenceissexy #instascience #undercoverengineering #instagram #nerd #nerds #mathematics #fact #knowledge #factsdaily #fun #industry #educateyourself #intelligence #didyouknow #sciencefacts #floating #nerds #engineer #mathematics #school #follow #learn #nerd #industry #educateyourself #density #instagram #knowledgeispower #intelligenceissexy #instascience #didyouknow #fact #mystery #anvil #intelligence #factsdaily #undercoverengineering #fun #knowledge #mercury #folowme #engineering #sciencefacts #instaschool #teaching
Tube mill process have many stages, composed from Rolling and welding (The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape), The cleaning and heating phase (tubes are then subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace), Cold- drawing process (tubes or pipes are coated with oxalic and soap solution), Finishing process (a pipe or tube is marked with grade of material, size, heat number and the stamp of third party inspection before passing out). . . 📢 Tag a friends to share knowledge... . ⏰ Turn on post notification and follow for brighter future… Follow me @undercover_engineering . #tube #pipes #manufacturing #welding #knowledge #knowledgeispower #instavideos #engineer #engineering #follow #folowme #school #instaschool #teaching #instavideo #instascience #undercoverengineering #instagram #rollers #heat #mathematics #fact #factory #factsdaily #fun #industry #educateyourself #video #didyouknow #sciencefacts #tube #engineer #mathematics #school #pipes #video #rollers #follow #factory #industry #welding #educateyourself #instagram #heat #knowledgeispower #instascience #didyouknow #fact #factsdaily #undercoverengineering #manufacturing #fun #instavideo #knowledge #folowme #engineering #instavideos #sciencefacts #instaschool #teaching

There is accumulation of positive charge on the surface of the earth, and the tension between the cloud and the earth is growing until the sudden stream of charged particles - lightning - equals the charge between the cloud and earth. Thunder is a sound effect, resulting in a lightning discharge. It is caused by the rapid heating and expansion of the air in the lightning path. . Lightning protection is simple. In the storm we do not stay open in the open area, especially on unprotected heights.If we have to be under the tree during the storm, we do not stand close to the trunk and our feet are close together. During the storm we do not swim in the water and we do not ride in the boat. The metal body of a car or aircraft represents a Faraday cage that protects the occupants from the effects of possible lightning. . BTW, the temperature of the air around the lighting is 30,000 ° C. . . 📢 Tag a friends to share knowledge... . ⏰ Turn on post notification and follow for brighter future… Follow me @undercover_engineering . #lightning #extreme #danger #protectyourself #knowledge #knowledgeispower #learn #engineer #engineering #follow #folowme #school #instaschool #teaching #bridge #instascience #undercoverengineering #instagram #funny #funfacts #mathematics #fact #storm #factsdaily #fun #destruction #educateyourself #thunder #didyouknow #sciencefacts #bridge #engineer #mathematics #school #follow #learn #funny #extreme #educateyourself #sciencefacts #instagram #knowledgeispower #instascience #didyouknow #fact #factsdaily #storm #undercoverengineering #protectyourself #funfacts #fun #knowledge #thunder #folowme #engineering #lightning #destruction #danger #instaschool #teaching

Did you know the ice is good electrical insulation with low thermal conductivity? Basically this means that ice is a good insulator against cruel frost, i.e. can protect plant seedlings or polar traveler. Unfortunately, it also means that if it rains at an ambient temperature of 0 °C, it could be a problem for the trolleybus and similar electric vehicles because the frost insulates overhead wires. A thin crust is formed on wires, which will not come into contact with contact shoes. . . 📢 Tag a friends to share knowledge... . ⏰ Turn on post notification and follow for brighter future… Follow me @undercover_engineering . #ice #snow #frost #electricity #knowledge #knowledgeispower #learn #engineer #engineering #follow #folowme #school #instaschool #teaching #explosion #instascience #undercoverengineering #rain #funny #funfacts #mathematics #fact #technology #factsdaily #fun #answer #educateyourself #discover #didyouknow #sciencefacts #engineer #mathematics #school #ice #learn #follow #explosion #funny #electricity #educateyourself #rain #knowledgeispower #instascience #snow #didyouknow #fact #answer #factsdaily #technology #undercoverengineering #fun #funfacts #knowledge #frost #folowme #discover #engineering #sciencefacts #instaschool #teaching
After poorly executed reactor tests in electricity production mode that were influenced by several factors, there was xenon poisoning in the reactor, which had reduced the reactor power for a long time. In order to improve reactor power, operators attempted to bypass xenon poisoning, and at the request of the experiment manager, almost all the control rods were pulled out, resulting in an exponential increase in reactor power and evaporation of the water in the water channels of the reactor at some point. At that moment, the first smaller explosion occurred because the steam generated broke the reactor and mixed the fuel with the graphite moderator. The resulting mixture was rapidly superheated and was able to form pure hydrogen from the steam by means of a thermochemical reaction. The second, much stronger, explosion occurred with an exothermic reaction between hydrogen and air. The resulting explosion ruptured the entire reactor hall and dispersed the mixture of fuel and other radioactive parts from the reactor into a wide area... . . So the lesson, which follows: Be careful with the pressure cookers and not everything that looks ecological is really safe… . . 📢 Tag a friends to share knowledge... . ⏰ Turn on post notification and follow for brighter future… Follow me @undercover_engineering . #nuclear #chernobyl #russia #science #knowledge #knowledgeispower #learn #engineer #engineering #follow #folowme #school #instaschool #teaching #explosion #instascience #undercoverengineering #hydrogen #funny #funfacts #mathematics #fact #technology #factsdaily #fun #answer #educateyourself #discover #didyouknow #sciencefacts #engineer #mathematics #science #school #follow #learn #explosion #funny #hydrogen #educateyourself #nuclear #russia #instascience #didyouknow #knowledgeispower #fact #chernobyl #answer #factsdaily #technology #undercoverengineering #fun #funfacts #knowledge #folowme #discover #engineering #sciencefacts #instaschool #teaching
Hydrogen production Hydrogen is the lightest and simplest gaseous chemical element that forms the bulk of the mass in the universe. However, on its own, it is very limited on Earth, so it must be produced and recovered from other compounds. There are many ways to obtain it, the most well known is the electrolysis of water that occurs when a DC electric current passes through a liquid that causes chemical changes on the electrodes. . Another very well represented method is thermochemical reactions of water vapor with other elements. When at high temperature there is a "decomposition" of water vapor, which can be described by oxidation of the metal / acid formation (the bonding of the oxide to the relevant element) and the isolation of hydrogen. . Nuclear reactor RBMK (Chernobyl type) Reactor RBMK (russian: Реактор Большой Мощности Канальный – Reaktor Bolšoj Moščnosti Kanalnyj, english: high power channel reactor) also known as the Light-Water-cooled Graphite-Moderated Reactor (LWGR), is a Soviet nuclear reactor built on the territory of the former USSR. It is a graphite moderated and water-cooled brewing reactor in which fuel rods with natural or slightly enriched uranium are stored in channels. . Its constructional advantage was that it had an uneven and vary neutron flux distribution so the fuel could be exchanged during its operation. Another advantage is that the reactor is a breeder/fertile type, i.e. in the reaction, besides other products, plutonium is produced, which can be extracted from the spent fuel and used for the production of nuclear weapons. . On the other hand, fluctuating neutron flux distribution increases the reactor's unstable reaction and increases demands for operator quality. Its considerable disadvantage is instability in case of overheating and also a small supply of water inside the circuit, which in the case of overheating immediately evaporates and the reactor has lost its cooling capacity. . I apologize for such a long explanation, but to understand the complex problem, a broad knowledge of many disciplines is needed. . 📢 Tag a friends to share knowledge... . ⏰ Turn on post notification and follow for brighter future… #engineer #mathematics #science #school #follow #learn #funny #hydrogenwater #hydrogen #educateyourself #nuclear #russia #instascience #didyouknow #knowledgeispower #fact #chernobyl #factsdaily #technology #undercoverengineering #fun #funfacts #knowledge #dictionary #folowme #discover #engineering #sciencefacts #instaschool #teaching

For this reason it is necessary for the ships to have a large contact area with water.  In the final consequence, ships are hollow inside, which can then be filled with cargo. The overall density of the entire ship is thus, depending on the volume, smaller than the water itself. Which is another fact that can be said that boats are floating on the surface. As was said before, the main goal is to maximize the contact surface of the object with water. For this reason, metal objects whose density is larger than waters' may float. . There are ships that can regulate their dive by filling (increase weight) and discharging (decrease weight) tanks inside their body. As the submarine dives, the ballast tanks are flooded with water and the air in the ballast tanks is vented from the submarine until its overall density is greater than the surrounding water and the submarine begins to sink (negative buoyancy) . . . 📢 Tag a friends to share knowledge... . ⏰ Turn on post notification and follow for brighter future… Follow me @undercover_engineering . . #ship #army #submarine #science #knowledge #knowledgeispower #navy #engineer #engineering #follow #folowme #school #instaschool #teaching #nature #instascience #undercoverengineering #diving #funny #funfacts #mathematics #fact #technology #factsdaily #fun #answer #commonsense #discover #didyouknow #sciencefacts #navy #submarine #engineer #mathematics #science #school #follow #funny #ship #nature #commonsense #knowledgeispower #instascience #didyouknow #fact #answer #factsdaily #technology #undercoverengineering #fun #funfacts #knowledge #diving #folowme #discover #engineering #army #sciencefacts #instaschool #teaching
Archimedes’ Law or Archimedes’ Principle says the buoyant force is equal to the weight of the displaced water. So, if the weight of the water displace is less then the weight of the object, the object will sink. Otherwise the object will float, with the weight of the water displaced equal to the weight of the object. So it also depends on the surface of the object that is in contact with water. The more water the object displace, the greater the buoyancy force will affect it. . . 📢 Tag a friends to share knowledge... . ⏰ Turn on post notification and follow for brighter future… Follow me @undercover_engineering . . #ship #principles #law #science #knowledge #knowledgeispower #learn #engineer #engineering #follow #folowme #school #instaschool #teaching #nature #instascience #undercoverengineering #lostinspace #funny #funfacts #mathematics #fact #technology #factsdaily #fun #dictionary #commonsense #discover #didyouknow #sciencefacts #engineer #mathematics #science #school #follow #learn #funny #ship #principles #lostinspace #nature #commonsense #knowledgeispower #instascience #didyouknow #fact #factsdaily #technology #undercoverengineering #fun #funfacts #knowledge #dictionary #folowme #discover #engineering #law #sciencefacts #instaschool #teaching
