What is the efficiency of a cycle consisting of two isochoric and two adiabatic lines, if the volume of the ideal gas changes 10 times within the cycle? The working substance is nitrogen. [(10)0.4 = 2.5]
Options:
Answer:
C
Solution:
Otto-type cycle: η = 1 - (Vmin/Vmax)γ - 1. N2 is diatomic, γ = 1.4: η = 1 - (1/10)0.4 = 1 - 1/2.5 = 0.6 = 60%. Matches (c).
