An adiabatic gas turbine expands air at 1,000kPa and 500C to 100kPa and 150C. Air enters the turbine through 0.200m^2 opening with an average velocity of 40 m/s and exhausts through a 0.910m^2 opening.
Determine
a) the mass flow rate of air through the turbine (kg/s)
b) the power produced by the turbine (kW)
