A one stage axial compressor (Rotor + Stator) takes in air from cond stagnation pressure and temperature Po1= 101.3 kPa & To1=278 K. At cc 30°= a3 also. Stage flow coefficient and stage at mean radius is aj = flow area at inlet is A1 = 0.372 m². Determine: (a) The axial velocity th rate m; and (c) The power (kW) W required to drive the compressor.

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.
