If p1 is the pressure of air entering the L.P. cylinder and p3 is the pressure of air leaving the H.P. cylinder, then the ratio of cylinder diameters for a single acting, two stage reciprocating compressor with complete intercooling is given by

Answer: Option D

If p₁ is the pressure of air entering the L.P. cylinder and p₃ is the pressure of air leaving the H.P. cylinder, then the ratio of cylinder diameters for a single acting, two stage reciprocating compressor with complete intercooling is given by $$\frac{{\text{D}}_1}{{\text{D}}_2}={\left(\frac{{\text{p}}_3}{{\text{p}}_1}\right)}^{\frac{1}{4}}$$
