250 kg / min of water are fed at 40 bar and 500 ° c to a turbine that develops a power of 1,500 kw. the operation of the turbine is adiabatic and the water leaves it at a pressure of 5 bars. the water that leaves the turbine passes through a heater where it is reheated isobarically to its initial temperature. despise the change of kinetic energy.
a) write the energy balance for each machine and for the overall process and justify each term you cancel.
b) is the steam that comes out of the turbine wet, saturated or overheated? justify your answer
c) calculate the temperature of the steam leaving the turbine.
d) calculate the amount of heat exchanged in the heater.
