Compressors, Gas Turbines and Jet Engines

For a two stage reciprocating compressor, compression from p₁ to p₃ is with perfect intercooling and no pressure losses. If compression in both the cylinders follows the same polytropic process and the atmospheric pressure is p_a, then the intermediate pressure p₂ is given by

A) $${{\text{p}}_2} = \frac{{{{\text{p}}_1} + {{\text{p}}_3}}}{2}$$ B) $${{\text{p}}_2} = \sqrt {{{\text{p}}_1}{{\text{p}}_3}} $$ C) $${{\text{p}}_2} = {{\text{p}}_{\text{a}}} \times \frac{{{{\text{p}}_3}}}{{{{\text{p}}_1}}}$$ D) $${{\text{p}}_2} = {{\text{p}}_{\text{a}}}\sqrt {\frac{{{{\text{p}}_3}}}{{{{\text{p}}_1}}}} $$

Answer & Solution

Correct Answer: Option B

For a two stage reciprocating compressor, compression from p₁ to p₃ is with perfect intercooling and no pressure losses. If compression in both the cylinders follows the same polytropic process and the atmospheric pressure is p_a, then the intermediate pressure p₂ is given by $${{\text{p}}_2} = \sqrt {{{\text{p}}_1}{{\text{p}}_3}} $$
