p/Pa 40. Pressure (p)-volume (V) indicator diagram of a cyclic process 12→3→1 consists of a straight line 1→2, an adiabatic 2-3 and an isotherm 3-1. Pressure (p)-volume (V) indicator diagram of another cyclic processes 1-3 4 1 consists of an isotherm 1-3, an isobar 3→4 and an adiabatic 4→1. If efficiencies of these two processes are Ni and 72 respectively, determine the efficiency of the cycle 1→2-3→4 1.
