6.2 Isobaric Cooling and Condensation of R134a 2 kg of superheated R134a at p = 1 MPa, T = 70C undergo an isobaric cooling process to saturated vapor (state 2), saturated liquid (state 3) to compressed liquid state at T = 24C. 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. Use the tables on pages 19-22 of our booklet. There is no compressed liquid table available, hence for state 4 use the approximation based on saturation data.
