4 kg/s of air enters steadily at 20°C through a heat
exchanger at a velocity of 35 m/s where its
temperature is raised to 900°C. It then enters a turbine
with the same velocity of 35 m/s until the temperature
is 700°C and 70 m/s. Calculate the heat transfer rate in
the heat exchanger and power output of the adiabatic
turbine in kW.
