A Student cycle engine is analyzed using the cold air-standard method. Given the definition of each process in the cycle, determine the thermal efficiency of the engine for each set of defined ratios listed below. All ratios are given as the larger value over the smaller one.--Given Values--Process 1-2 = Isentropic compression & volume ratio=rv12Process 2-3 = Isobaric compression & volume ratio=rv23Process 3-4 = Isometric heat addition & pressure ratio=rP34Process 4-5 = Isometric heat addition & temperature ratio=rT45Process 5-6 = Isentropic expansionProcess 6-1 = Isometric coolingEnter the equation for W12(m, cp, cv, T1,T2,T3,T4,T5,T6)
