3.9 kg/s of air expands through a turbine from 8 bar, 800 K to 1 bar, 400 K. The inlet velocity is small compared to the exit velocity of 90 m/s. Heat transfer between the turbine and its surroundings and potential energy effects are negligible. Using Table A.20, take the specific heat of air at the average temperature. What is the power developed by the turbine? Express the answer in kW.
A refrigeration cycle operating as shown below has a coefficient of performance = 2. For the cycle, Qout = 260 kW. What is the input power, Wcycle? Express the answer in kW. Hot body lout System Qin w cycle Cold body
