A two-phase liquid-vapor mixture of H2O with an initial quality of 25% is contained in a piston-cylinder assembly. The mass of the piston is 40 kg, and its diameter is 10 cm. The atmospheric pressure of the surroundings is 1 bar. The initial and final positions of the piston are shown on the diagram. As the water is heated, the pressure inside the cylinder remains constant until the piston hits the stops. 4.5 cm Heat transfer to the water continues until its pressure is 3 bar. Friction between the piston and the cylinder wall is negligible. Determine the total amount of heat transfer, in J. 1 cm Diameter 10 cm. Mass = 40 kg Patm= 100 kPa Initial quality x₁ = 25% A two-phase liquid-vapor mixture of H2O with an initial quality of 25% is contained in a piston-cylinder assembly.
