Problem on Ideal gas process

A) Air at 4MPa and 3000C enters a will insulated turbine operating at steady state with negligible velocity. The air expands to an exit pressure of 100KPa. The exit velocity and temperature are 90 m/s and 1000C respectively. The diameter of the exit is 0.6m. Determine the power developed by the turbine (in KW). You may assume air behaves like an ideal gas throughout the process.
