A steam turbine in a small electric power plant is designed to accept 4500 kg/hr of steam at 60 bar and 500°C and exhaust the steam at 10 bar. Heat transfers to the surroundings 1Tsurr 5 300K2 at a rate of 69.86 kW. Answer the following questions:

(a) Calculate the maximum powerthat the turbine can generate.

(b) In this case, what is the exit temperature of the steam?

(c) You know that the isentropic effi ciency of the turbine is actually 66.5%. What is the actual power produced?

(d) Do you expect the exit temperature to be higher or lower than that calculated in part (a).
Explain. (Assume the heat transfer does not change.)

(e) What is the actual exit temperature?
