A closed rigid cylindrical vessel (internal diameter = 2 ft and internal height = 10 ft) has R-134a at x = 0.95 and 40 oF. The vessel is heated up to 100 oF. Assume that heat loss from the vessel is negligible. Kinetic and potential effects are negligible. Determine 1) the final pressure in psi [lbf/in2], 2) the mass of R-134a in lbm, 3) the heat transfer in Btu for this process and discuss its direction (if the heat is added to or rejected from the system), 4) the work transfer in Btu for this process and discuss its direction (if the work is done by or on the system), and 5) draw the process in T-v (temperature-specific volume) diagram.
