I have a question that I have no idea where to start for, please show working if you can, or atleast help me with the steps. I understand that with the inital pressure you can from tables find the initial temperature, but where do i go from there? See below
A system of refrigerant R-22 undergoes a power cycle composed of the following processes.
Process 1 -> 2: Constant pressure heating at 20 bar, from saturated vapour - to 1.5× its initial
volume.
Process 2 -> 3: Constant volume cooling to a saturated vapour state.
Process 3 -> 4: Isothermal compression to the original volume.
Process 4 -> 1: Constant volume heating.
Neglecting kinetic and potential energy effects, determine the efficiency of this cycle.
Thanks very much
