Air (an ideal gas) is the working fluid in a steady-state turbine operating with the following inlet and outlet conditions:
T1=1800K
T2=1000K
m= 2.9 kg/s
If it outputs 2,065 kW of power, what is the rate of heat transfer in kW during operation? [Do not assume constant specific heats.] the correct answer is -711kW
could you help me work this out
