Question

What is the efficiency of a cycle made of two isochoric and two adiabatic lines, if the volume of the ideal gas changes 32 times within the cycle? The working substance is hydrogen gas (γ = 1.4). [(32)^0.4 = 4]

Options:

Answer:

A

Solution:

η = 1 - (V_min/V_max)^{γ - 1} = 1 - (1/32)^0.4 = 1 - 1/4 = 0.75 = 75%. Matches (a).
