Determine the entropy production rate as 0.0500 kg/s of air flows through a vortex tube from an inlet pressure of 1.00 MPa.
Both hot and cold side exit pressures are 101.3 kPa, and the hot side temperature is 50.0°C while the cold side temperature is -40.0°C.
Two thirds of the inlet mass flow rate passes through the hot side exit.
Assume constant, specific heat, ideal gas behavior and neglect any changes in kinetic and potential energy.
