Compressors Gas Dynamics and Gas Turbines - Engineering

Q1:

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 intercooler 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)

A D1/D2 =  p1p2

B D1/D2 =  p1/p2

C D1/D2 =  p2/p1

D none of these

ANS:C - D1/D2 =  p2/p1
