Water has a greater heat-absorbing capacity than most common extinguishing agents. The basic operation of the steam turbine is similar to the gas turbine except that the working fluid is water and steam (with a phase change) . By condensing the working steam to a liquid (inside a condenser) the pressure at the turbine outlet is lowered and the energy required by the feed pump consumes only 1% to 3% of the turbine output power and these factors contribute to a higher efficiency for the cycle. How does one litre of water turn into steam? This is the energy release caused by a sudden change in state of water, turning into vapor. Some of the steam then goes to an open feed water heater and the balance is reheated to (400 Co), after which it expands in the LP turbine to (0.07 bar). Obviously, at the same pressure, the higher the temperature the lower the density of water vapor. Steam takes up a lot more space (it has a greater volume) than liquid water because water molecules in steam are more widely dispersed. This means that under ideal conditions, 1 part of liquid water expands to 1700 times the volume as steam when boiled. As the water heater operates you can watch the pressure increase in the system.

The volumetric temperature coefficient of water is given as water : 0.00021 (1/oC) in other words, this is water's coefficient of volumetric expansion as it is heated. CIBSE tables? Generally, the expansion of water into steam depends greatly on temperature and atmospheric pressure. How much water does it take to make a pound of steam? T_out = theoretical temperature of the steam exiting the cylinder after expansion, assuming perfect adiabatic expansion and no condensation. However, the exergy balance on boiler (heat exchanger) includes exergy of fuel which is to be determined. (Brandford White 2019). * Required. When the steam is expanded through a high-pressure ratio, as in large steam turbines, the steam can begin to condense in the turbine when the temperature of the steam drops below the saturation temperature at that pressure. Here we provide a more theoretical discussion of how we might calculate the pressures that can be expected to occur in a water tank due to thermal expansion.
