Answer to Question #136520 in Chemical Engineering for abhi sharma

Question

A piston-cylinder device contains 3.5 kg of water. Initially the water is a saturated
liquid at 105 °C (State 1). The water is heated until the piston just touches the stops, at
which point the volume is 2.18 m3 (State 2). Heating of the system continues until a
pressure of 1000 kPa is reached (State 3).
(a) Calculate the work done by the device during the process from state 1 to state 3
(kJ).
(b) Calculate the heat transfer required for this process (kJ).
(c) Draw the process on a pressure - volume diagram with respect to the saturation
lines.
