An adiabatic gas turbine expands air at 1300 k Pa,
500 oC to 100 k Pa, 127 oC. Air enters the
turbine through a 0.4 m2 opening with an average velocity of
40 m/s and exhausts through a 1- m2 opening. Determine the
mass flow rate of air and the power output of the turbine. If the output shaft
of the turbine rotates at 10000 rpm calculate the torque developed by the
turbine.

An adiabatic gas turbine expands air at 1300 kPa and 500°C to 100 kPa and 127°C. Air enters the turbine through a 0.2-m2 opening with an average velocity of 40 m/s, and exhausts through a 1-m2 opening. Determine the mass flow rate of air through the turbine and (b) the power produced by the turbine.
