The 7fa gas turbine manufactured by general electric is reported to have an efficiency of 35.9% in the simple-cycle (brayton) mode and to produce 159 mw of net power. the pressure ratio is 14.7, the turbine inlet temperature is 1,288 c. the mass flow rate through the turbine is 1,536,000 kg/h. taking the ambient conditions to be 20 c and 100 kpa (as the state before the compressor), determine the isentropic efficiency of the turbine and the compressor. also, determine the thermal efficiency of this gas turbine if a regenerator with, an effectiveness of 65 percent is added.

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.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
