A valve in an air handling system has a mass flow rate of 2.90 kg/min and a minor loss coefficient of 11.56. The valve inlet temperature is 20.0°C and the valve is insulated.
The inlet and exit pressures of the valve are 1.66 and 0.300 MPa, respectively. The air velocity through the valve is 2.70 m/s.
Assuming air to be an ideal gas with constant specific heats, determine the exit temperature and entropy production rate of the valve.
