Steady-state operating data for a simple steam power plant are provided in Fig. P4.102. Stray heat transfer and kinetic and potential energy effects can be ignored. Determine the (a) thermal efficiency and (b) the mass flow rate of the cooling water, in kg per kg of steam flowing.

Determine (a) thermal efficiency and (b) the mass flow rate of the cooling water, in kg per kg of steam flowing. (it says kg per kg in the book, it probably wants kg per min or sec)
