• # question_answer For a two-stage reciprocating compressor, compression from pressure ${{p}_{1}}$ to ${{p}_{3}}$ is with perfect intercooling and no pressure losses. If compression in both cylinders follows the same polytropic process and the atmospheric pressure is ${{p}_{a'}}$ then the intermediate pressure ${{p}_{2}}$ is given by:                      A) ${{p}_{2}}=({{p}_{1}}+{{p}_{3}})/2$          B) ${{p}_{2}}=\sqrt{{{p}_{1}}.{{p}_{3}}}$C) ${{p}_{2}}={{p}_{a}}\frac{{{p}_{3}}}{{{p}_{1}}}$            D) ${{p}_{2}}={{p}_{a}}.\sqrt{{{{p}_{3}}}/{{{p}_{1}}}\;}$
