Air enters a turbine at a mass flow rate 10 lbm/s and at 200 psiand 2700 R. If the air leaves the turbine at 14 psia and 1520 R.Heat is lost from the turbine at 400 Btu/s. if the power producedby the turbine is used to drive an R-134a compressor by a rotatingshaft connecting the two devices. R-134a enters the compressor as asaturated vapor at 30psia and leaves at 200 psia and 280 F.Neglecting kinetic and potential energy.
a) What is the power produced by the turbine (hp)?
b) What is the mass flow rate of the R-134a (lbm/s)?
c) the increase in mass flow rate of R-134a that could beachieved if the turbine were adiabatic (lbm/s)?
