Can you believe that 0.800 kg/s of air at 60.0°C and 1.50 MPa is mixed in an open heat exchanger with 1.50 kg/s of air at 20.0°C and 1.50 MPa to produce an outlet mixture at 30.0°C at 1.50 MPa?
Determine the second law availability efficiency of this heat exchanger.
Neglect all kinetic and potential energy effects, and take the local environment (ground state) to be 0.101 MPa and 20.0°C.
