Two boilers of equal evaporative capacities generate steam at the same pressure of 15 bar (1.5 MPa) to a common pipe line. One boiler produces superheated steam at 150°C and the other produces wet steam If the mixture is just dry and saturated, find the dryness fraction of the wet steam from the second boiler. Steam Properties: At 15 bar (1.5 MPa), 250°C h = 2925 kJ/kg At 15 bar (1.5 MPa) hf = 845 kJ/kg hig hfg = 1947 kJ/kg h, = 2792 kJ/kg A. 0.9315 B. 0.8425 C. 0.7142 D. 0.6573

Question
Two boilers of equal evaporative capacities generate steam at the same pressure of 15 bar (1.5 MPa) to a common pipe line. One boiler produces superheated steam at 150°C and the other produces wet steam If the mixture is just dry and satrated, find the dryness fraction of the wet steam from the second boiler. Steam Properties: At 15 bar (1.5 MPa), 250°C h = 2925 kJ/kg At 15 bar (1.5 MPa) he = 845 kJ/kg hfg = 1947 kJ/kg = 2792 kJ/kg hg = A. 0.9315 B. 0.8425 C. 0.7142 D. 0.6573
