In an isobaric process, 1 litre of compressed liquid water at p 10 MPa, T 40°C is heated to saturated liquid state (State 2), then evaporated to saturated vapor state (State 3), and then further heated to T4-450°C. Determine temperature, pressure, specific volume, internal energy, enthalpy and entropy in the four states; collect the data in a table. Then determine the work and the heat for the process. For state 1, also use the approximation based on saturation data to...
