2) A two-phase, liquid-vapor mixture of H20, initially at x=30% and a pressure of 100 KPa, is contained a piston-oylinder assembly. The mass of the piston is 10 kg and its diameter is 15 cm. The pressure a the surroundings is 100 kPa. As the water is heated, the pressure inside the cylinder remains constan until the piston hits the stops. Heat transfer to the water continues at constant volume until the pressue is 150 KPa. Friction between the piston and the cylinder wall and kinetic and potential energy effects an negligible. For the overall process of the water, determine the work and heat transfer, each in kJ. Wa. itially A W=0.206 kJ, Q= 1.53 kJ BW=0.106 kJ, Q= 1.53 kJ CW=0.106 kJ, Q= 1.43 kJ D.

Question
2) A two-phase, liquid-vapor mixture of H20, initially at x=30% and a pressure of 100 kPa, is contained in a piston-cylinder assembly. The mass of the piston is 10 kg, and its diameter is 15 cm. The pressure of the surroundings is 100 kPa. As the water is heated, the pressure inside the cylinder remains constant until the piston hits the stops. Heat transfer to the water continues at constant volume until the pressure is 150 kPa. Friction between the piston and the cylinder wall and kinetic and potential energy effects are negligible. For the overall process of the water, determine the work and heat transfer, each in kJ. Water, initially at -30%. Piston D-15 cm 10 kg p00 P A W = 0.206 kJ, Q = 1.53 kJ B.
