Aturbine operates on superheated steam that enters at 80 bar absolute and 500˚c, and leaves the turbine at 7.5 bar absolute and 250˚c. the flow rate of the steam is 400 kg/min and the turbine operates adiabatically. the steam exiting the turbine goes to a heater, which is supplied with 2000
2kw of energy. the steam leaves the heater at 5 bar absolute. all of the pipes through which the
steam flows are 0.5 m (id) in diameter.
a. how much power is produced by the turbine? (4 marks)
b. what is the temperature of the steam leaving the heater? (4 marks)
c. what is the velocity (m/s) of the steam entering the turbine? (3 marks)
d. to what temperature can the steam at 80 bar be cooled before a liquid will appear?
