8.18 computer in the preliminary design of a power plant, water is chosen as the working fluid. it is determined that the turbine inlet temperature and pressure should be 560°c and 12,000 kpa, respectively. the quality of steam exiting the turbine should be at least 90%. if the isentropic turbine efficiency is 84%, determine the minimum condenser pressure allowable, in kpa.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
