Steam at 20 bar, 3600C is expanded in a steam turbine to 0.08 bar. It then enters a condenser, where it is condensed to saturated liquid water. A pump feeds back the water into the boiler.

(a) Assuming ideal processes, find per kg of steam the network and the cycle efficiency.

(b) If the turbine and the pump have 80% efficiency, find the percentage reduction in the network and cycle efficiency.
