Determine the entropy production rate and heat transfer in a newly designed valve with 1.10 kg/s of an incompressible hydraulic oil flowing through it.
The minor loss coefficient of the valve is 26.3, and the inlet and outlet oil temperatures are 53.0 and 49.0°C, respectively.
The surface temperature of the valve is constant at 46.0°C. The flow velocity through the valve is constant at 3.00 m/s, and the specific heat of the oil is 1.13 kJ/(kg · K).
