Consider the same problem in which an axial compressor with a mean diameter of 0.8 m is being designed to run at 3000 rpm. The whirl velocities at the inlet and outlet are 5m/s and 30 m/s, respectively. The air mass flow rate through the compressor is 2 kg/s at a temperature of 27 °C. Assume C, of air equal to 1000 J/kg-K and Cy = 718 J/kg-K. %3D The temperature change is equal to

Superheated steam at 40 bar absolute and 500°C flows at a rate of 250 kg/min to an adiabaticturbine, where it expands to 5 bar. The turbine develops 1500 kW. From the turbine thesteam flows to a heater, where it is reheated isobarically to its initial temperature. Neglectkinetic energy changes.(a) Write an energy balance on the turbine and use it to determine the outlet streamtemperature.(b) Write an energy balance on the heater and use it to determine the required input (kW) tothe steam.(c) Verify that an overall energy balance on the two-unit process is satisfied.(d) Suppose the turbine inlet and outlet pipes both have diameters of 0.5 meter. Show that itis reasonable to neglect the change in kinetic energy for this unit.
