If the clearance ratio for a reciprocating air compressor is 'K', then its volumetric efficiency is given by

Answer: Option B

If the clearance ratio for a reciprocating air compressor is 'K', then its volumetric efficiency is given by $$1+\text{K}-\text{K}{\left(\frac{{\text{p}}_2}{{\text{p}}_1}\right)}^{\frac{1}{\text{n}}}$$
