B. Pure Substance Processes 1. A prototype boiler that contains 5 kg of saturated steam at a pressure of 482.5kPa. Determine the amount of heat which must be rejected in order to reduce the quality to 60%. (a) What will be the pressure and temperature of the steam at this new state? Compute for the (b) heat, (c) internal energy, (d) entropy, and (e) enthalpy at this new state. Note: Consider a constant pressu 2. Compute for the (a) dryness factor, (b) internal energy. (c) enthalpy, and (d) entropy of a saturated water at 21.225 MPa. 3. Three kilograms of water at 35 degrees Celsius are placed in a piston under 4.335MPa (State 1). Heat is added to the water at constant pressure until the piston reaches a stop at a total volume of 0.55 m³ (State 2). Most heat is added at constant volume until the temperature of water reaches 425 degrees Celsius (State 3). Determine (a) the quality of fluid and the mass of the vapor at State 2, and (b) the pressure of the fluid at State 3.
