Agas-turbine power plant operates on the simple brayton cycle with air as the working fluid and delivers 32 mw of power. the minimum and maximum temperatures in the cycle are 310 and 900 k, and the pressure of air at the compressor exit is 8 times the value at the compressor inlet. assuming an isentropic efficiency of 80 percent for the compressor and 86 percent for the turbine, determine the mass flow rate of air through the cycle. account for the variation of specific heats with temperature.

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.
