Water vapor at 10 mpa, 600°c enters a turbine operating at steady state with a volumetric flow rate of 0.36 m3/s and exits at 0.1 bar and a quality of 92%. stray heat transfer and kinetic and potential energy effects are negligible. determine for the turbine (a) the mass flow rate, in kg/s, (b) the power developed by the turbine, in mw, (c) the rate at which entropy is produced, in kw/k, and (d) the isentropic turbine efficiency

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.
