Animation: How a counterflow shell and tube heat exchanger works. 1) The exchanger consists of a large outer shell (light gray) with tubes running through it (dark gray). 2) A hot fluid enters the tubes from the top left and exits from the bottom right. 3) A cooler fluid passes the...
A car's air conditioning works by manipulating pressure and temperature to move refrigerant between a liquid and gaseous state. The refrigerant enters the evaporator as a liquid, and the heat of the car transforms it into a gas. In its gaseous state, refrigerant can absorb heat. The refrigeran...
An actual igniter placed inside the chamber would be prone to damage from heat,fireand fuel. That's why many spud guns use two metal points within the chamber to create the spark. Current from the ignition device -- often agrillstarter orstun gun-- travels into the chamber, and a spark...
Water heaters can be repaired if you identify the cause and then reading the water heater diagram with some tools the problem can easily be fixed. How Long Does It Take To Get Chlorine Out Of Well Water The high concentration of chlorine in well water is not safe for drinking, nor is it...
However, the standard model for air-conditioned seats, developed by scientists at the Department of Energy's National Renewable Energy Laboratory (NREL), works like this: The fabric of the car seat is a porous mesh, so air can flow through it. Multiple fans inside the seat produce air ...
How Solar Water Heater Works? Initial solar water heaters were basically large metal containers painted in black because black color is a good conductor of heat and absorbs a lot of heat getting heated quickly. As the container got heated with the heat of the sun, water stored in these conta...
Where an air conditioner works like a fridge, expanding and then compressing a coolant chemical to shift heat from inside a building to outside, an air cooler sucks in hot air, passes it through or near to water to cool it down, and then blows it back out into the room. There are ...
Cooling system diagram. Click for a larger imageThe coolant flows through the engine where it absorbs the heat and into the top of the radiator. The radiator is built of many flat aluminum tubes surrounded by fins. The air passing through the radiator cools down the coolant as it flows ...
shown in the diagram below, is thetop-heading-and-bench method. In this technique, workers dig a smaller tunnel known as aheading. Once the top heading has advanced some distance into the rock, workers begin excavating immediately below the floor of the top heading; this is abench. One adv...
The most popular way to make steam is to heat water by burning coal. It's also possible to use controlled nuclear reactions to turn water into steam. You can read about the various types of power stations in How Hydropower Plants Work, How Wind Power Works and How Nuclear Power Works. ...
