How much steam pressure is generated from 1 pound of water at 675F?

Assuming a saturated condition (some liquid and some vapor) the pressure at 675°F is around 2700 psia. The amount of water doesn't matter.

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.
What is the density of high pressure steam?
will density of water is equal to density of steam at high pressures and temperatures
How much steam pressure would a five inches diameter by twelve inches long with six inches of water in it?
The steam pressure (assuming this is a closed container) will be entirely dependent on the temperature. Look up steam tables to get the pressure of saturated steam at various temperatures.
What does steam to steam humidifier mean?
A steam to steam humidifier uses steam, typically generated by a boiler located in the building, to heat water for creating steam to use for humidification. The most common reason for doing this is that boiler steam usually contains water treatment chemicals that people do not want to breathe. Domestic, or Potable water, is often used as the water supply for the humidification steam. Reverse Osmosis or Deionized Water streams may also be used for humidification, if available, if dust particles are a concern.
How does a dry steam cleaner work?
A dry steam cleaner works by turning water into dry steam vapor. The cleaner heats water under high pressure which turns the water into a vapor that has very little moisture.
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 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.
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 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

How does steam conduct electricity?
Steam generates electricity by spinning turbines located within electromagnetic fields. The steam can be generated by heating water using many types of fuels, such as coal, gas, and oil, or through the heat generated from controlled nuclear reactions.
What is the most violent volcanic explosions generated from?
Boiler volcanoes are the most violent. Water is sometimes trapped in the porous rock of a volcano, and when the water gets hot enough, it turns to steam and creates enormous pressure.
How do plants maintain water pressure?
Water pressure in plants is caused by capillary action generated by the surface tension of its water.
Can an engine run on steam?
Yes. The early piston engines were all run on steam generated by coal which would boil water.
What is the process called in which water turns to gas?
The process when water changes into a gas is called evaporation. Evaporation occurs for pure water at 100 degrees celsius (-173 K) when water molecules begin to move around very rapidly and split up.
