Q. A tank of volume 0.05 m3 contains a mixture of saturated water and saturated steam at 200°C. The mass of the liquid present is 8 kg. The entropy (in kJ/kg K) of the mixture is (correct to two decimal places).
Property data for saturated steam and water are:
At 200°C, psat = 1.5538 MPa
v f = 0.001157 m3/kg, vg = 0.12736 m3/kg
sfg = 4.1014 kJ/kg K, sf= 2.3309 kJ/kg K
Ans: 2.45 – 2.55
