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.
Steam pressure can be used to run a steam turbine which generates electricity by converting the motion of magnets into voltage.
will density of water is equal to density of steam at high pressures and temperatures
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.
Steam is produced whenever water boils, which occurs at 100 degrees Celsius at standard pressure and temperature (boiling point changes at altitudes because of the pressure change, remember).
Do you have a pressure cooker in ur home ? If u hav then watch it, the steam energy causes the wistle to blow. James watt steam engine (train)
The Titanic had two four-cylinder, triple-expansion, inverted reciprocating steam engines and one low pressure Parsons turbine. Steam came from 29 boilers which used 159 coal burning furnaces. They were big. I'm not sure of the weight of the engines.Engine was 30 feet in height and weighed 1000 tons. The high-pressure cylinder was 54 inches in diameter and the Intermediate-Pressure cylinder was 84 inches in diameter and the low-pressure cylinder was 97 inches in diameter. The operating speed was 75rpm and stroke was 75 inches.The specifications of the engine room was: the Reciprocating-engine room 69 feet;the Turbine-engine room 57 feet; and the Electric-engine ROM 63 feet.There were twenty-four double ended boilers and five single ended boilers which were housed in six boiler rooms. The double ended boilers were 20 feet long, had a diameter of 15 feet 9 inches and contained six coal burning furnaces. The single ended boilers were 11 feet 9 inches long with the same diameter and three furnaces. Smoke and waste gasses were expelled through three funnels. (I believe one of the funnels was a fake.)
steam+steam engine=pressure
What you meant by this question is uncertain. If you are asking about the definition then Boiler steam pressure is the pressure developed by a water steam boiler, else if you are asking about the Rated boiler steam pressure then it is the safe operating pressure a boiler can operate, else if you are asking about Maximum boiler steam pressure then it is the maximum pressure that a boiler can produce with out failure.
If you heat steam under pressure you get "superheated steam" under higher than original pressure
Steam that was reduced in pressure from that at which it was generated in the boiler. Reducing the steam pressure can be accomplished by running it through a turbine or engine, a reducing valve or a regulator. Reduced pressure steam is often used for auxiliary equipment or heating systems after the primary process has been supplied steam at the generated pressure.
Steam boiler: Steam boilers under IBR means any closed vessel exceeding 22.75 liters in capacity and which is used expressively for generating steam under pressure and includes any mounting or other fitting attached to such vessel which is wholly or partly under pressure when the steam is shut off. Steam pipes: IBR steam pipe means any pipe through which steam passes from a boiler to a prime mover or other user or both if pressure at which steam passes through such pipes exceeds 3.5 kg/cm2 above atmospheric pressure or such pipe exceeds 254 mm in internal diameter and includes in either case any connected fitting of a steam pipe.
Assuming that the question relates to pressure washers, one can purchase steam and pressure washers from Karcher UK, Steam and Pressure and Steam Powered websites. They are also available from an Argos store.
Yes. But it is limited in control by the orifice size, pressure applied and piping diameter. In other words it is "fixed". An example would be the metering device in a refrigerant circuit, specifically an orifice or capillary tube. The same physics apply.
around 8mm, if we consider carbon steel 516-70 service material to be steam....
gumball who ivented high pressure steam broilers
The fittings THREADED are normally rated for 125 PSI but there are ratings over 3,000 PSI if needed such as high pressure steam applications Then one has to take temperature /pressure relationship into consideration higher temperature greater pressure
steam engine uses thermal energy to convert water into steam and then uses pressure of steam to move the engine .thus thermal energy into pressure and further pressure into mechanical energy.
