Question 1. If p₁, is the pressure of air entering the l.p. cylinder and p₂ is the pressure of air leaving the l.p. cylinder (or inter-cooler pressure), then the ratio of cylinder diameters for a single acting, two stage reciprocating air compressor with complete intercooling is given by (where d₁ = dia. of l.p. cylinder, and d₂ = dia. of h.p. cylinder)
Answer: Option C. -> D₁/D₂ = p₂/p₁
