Air enters an adiabatic steady-flow gas turbine at 650 K and 550 kPa and leaves at 430 K and 100 kPa. The mass flow rate of the  is 45.5 kg/s. Treat the air as an ideal gas and use average specific heats.

A. Neglecting the potential energy and kinetic energy at the inlet and outlet, determine the power (kW) produced by the turbine.

B. If the air enters the turbine through a pipe with a flow area of 0.07m² and exits through a 0.37-m² pipe, determine the in kinetic energy rate (kW) of the air.
