1 pound of water equals how much steam?
1 pound of water at sea level can produce approximately 26.8 cubic feet of steam.
What does one pound of steam weigh?
One pound of steam weighs the same as one pound of water, which is approximately 16 ounces or 0.45 kilograms.
What happens to steam after it has generated electricity?
After steam has been used to generate electricity in a power plant, it is condensed back into water. This condensed water is then returned to the boiler to be heated again and turned back into steam, creating a continuous cycle of generating electricity.
How is heat generated?
When water is heated, there is a relation between temperature and pressure at which the water and steam are in equilibrium. This applies up to 374 degC at which the corresponding pressure is 222 bar abs or 3220 psi abs. Beyond this temperature liquid water cannot exist and the steam is said to be supercritical. At any temperature between 100 degC and 374 degC there will therefore be a pressure at which steam is just formed and this is said to be dry saturated steam. It is saturated because if the temperature drops even slightly at the same pressure, steam will condense. If at this same pressure the steam is further heated, it is said to be superheated because it is at a temperature higher than dry saturated steam would be. Superheated steam is desirable for use in steam turbines, because it prevents formation of water droplets as the steam is expanded through the turbine-the droplets could damage the turbine blades. In the supercritical region above 374 degC steam will always exist whatever the pressure, so the concept of superheat does not apply here.
Is it possible to boil water by passing steam at atmospheric pressure?
No, passing steam at atmospheric pressure will not cause water to boil. Boiling occurs when the liquid reaches its boiling point temperature and vapor pressure overcomes the atmospheric pressure. Generally, steam at atmospheric pressure will only cause the water to heat up and potentially evaporate faster.
What is the Watered- Powered steam engine?
All of 'em! Though it's steam that does the work, and the steam is generated by boiling water in a pressure-vessel called... the Boiler. Any questions?
How many pound of steam does 1 gallon of water make?
One gallon of water weighs approximately 8.34 pounds. When water is converted to steam, it expands significantly; specifically, one pound of water can produce about 1,600 gallons of steam at atmospheric pressure. Therefore, 1 gallon of water can produce around 13,440 pounds of steam when fully vaporized.
How is steam produced in a boiler?
Steam is generated by heat from the combution of fuel in a furnace or by waste heat from a process. The heat is transferred to water in the boiler shell, which then evaporates to produce steam under pressure.
1 pound of water equals how much steam?
1 pound of water at sea level can produce approximately 26.8 cubic feet of steam.
How many pounds of water are needed to make one pound of steam?
Well, you seem like a very smart kid. Let me ask you something: if you had one pound of naiveness in one hand and one pound of idiocy in the other, which one weighs more? Let me tell you a secret: Its the same!
What does one pound of steam weigh?
One pound of steam weighs the same as one pound of water, which is approximately 16 ounces or 0.45 kilograms.
How is electricity generated by using coal?
The coal is burned to boil water. The high-pressure steam is passed through the blades of a turbine, which turns an electric power generator.
Is electricity fossil fuel?
Electricity itself is not a fossil fuel but, can be generated by steam turbines and generators where the steam has been generated by heating water in fossil fuel boilers.
What happens to steam after it has generated electricity?
After steam has been used to generate electricity in a power plant, it is condensed back into water. This condensed water is then returned to the boiler to be heated again and turned back into steam, creating a continuous cycle of generating electricity.
What does the steam boiler do?
Boils water to create high pressure steam.
What is the pressure of high pressure steam?
will density of water is equal to density of steam at high pressures and temperatures
Why does an electric kettle whistle when it's first turned on?
An electric kettle whistles when it's first turned on because of the steam generated as the water heats up. As the water reaches its boiling point, steam escapes through a small opening in the lid or spout, creating a pressure difference. This pressure forces the steam to vibrate, producing the whistling sound. The whistle serves as an audible signal that the water has reached its boiling point.
