An ideal gas expands in an adiabatic turbine from 1200 k and 900 kpa to 800 k. determine the turbine inlet volume flow rate of gas, in m3/s, required to produce turbine work output at the rate of 650 kw. the average values of the specific heats for this gas over the temperature range and the gas constant are cp = 1.13 kj/kgk, cv = 0.83 kj/kgk, and r = 0.30 kj/kgk.

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.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false
