The inter-cooler pressure, for minimum work required, for a two stage reciprocating air compressor, is given by (where p₁ = Intake pressure of air, p₂ = Inter-cooler pressure, and p₃ = Delivery pressure of air)

p₂ = p₁ × p₂

p₂ = p₁/p₃

p₂ = p₁ × p₃

p₂ = p₃/p₁

p₂ = p₁ × p₂

p₂ = p₁/p₃

p₂ = p₁ × p₃

p₂ = p₃/p₁
