Question:

A condenser in a power plant receives 5 kg/s steam at 15 kPa, quality 90% and rejects the heat to cooling water with an average temperature of 17◦C. Find the power given to the cooling water in this constant-pressure process, shown in Fig. P7.100, and the total rate of entropy generation when the condenser exit is saturated liquid.
