A pressure cooker is filled with 2.0 kg of liquid water at 30oC. Heat is added to the system, and the relief valve releases saturated water vapor when the pressure reaches 150 kPa. Model the system, and then use the model to plot the amount of heat transfer that occurs as the mass of the water present in the pressure cooker ranges from 1.95 kg to 1.00 kg
State e: outlet state; State 1: Initial State; State 2: Final State. Given: H2O; m1 = 2.0 kg; T1 = 30oC; P2 = Pe = 150 kPa; xe = 1.0 Assume: As no information is given and these terms are unlikely to be significant, W = 0, and kinetic and potential energy can be neglected. No flow into the system. V = constant. What will be an ideal response?
