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=rv12
Process 2-3 = Isobaric compression & volume ratio=rv23
Process 3-4 = Isometric heat addition & temperature ratio=rT34
Process 4-5 = Isobaric heat addition & temperature ratio=rT45
Process 5-6 = Isentropic expansion
Process 6-1 = Isometric cooling
