P-V diagram of otto cycle with its efficiency l Python

Objective: This the program to plot P-V diagram of otto cycle with it's efficiency. In otto cycle heat addition and heat rejection takes place at constant volume and compression and expansion takes place by reversible adiabatic process. p1,p2,p3,p4 are the pressure\'s at sec 1,2,3 and 4, v1,v2,v3,v4 are the volume\'s at at sec…
