Air flows steadily through a gas turbine. Air enters the turbine at 2MPa and 427 degrees C with a velocity of 20 m/s and leaves at 120kPa and 37 degrees C. The inlet and exit areas of the turbine are 0.001 and 0.008m^2 respectively. If the power output of the turbine is 140kW, determine:
1. Rate of heat loss from the turbine. (Assume constant specific heats)
