Saturated steam at 99.6 °C is heated to 350°C. Use the steam table provided to determine: a. The required heat input if 1 kg of steam undergoes the process in a variable-volume constant-pressure container. b. The work of expansion (in k) of the steam undergoing the process. c. The required heat input if a continuous stream flowing at 1 kg/s undergoes the process at constant pressure. d. Does your numeric answer to part c equal the sum of parts b and a? Explain why or why not. Given: 1 bar = 10 N/m, Q=AH, Q = AU, AH = AÙ + PAV, table B.7 in kJ/kg and m°/kg.
