Chemical Engineering Thermodynamics (MCQs)

# A two stage compressor is used to compress an ideal gas. The gas is cooled to the initial temperature after each stage. The intermediate pressure for the minimum total work requirement should be equal to the __________ mean of P₁ and P₂.(where, P₁ and P₂ are initial and final pressures respectively)
