A) It decreases with increase in ambient temperature
B) It increases with decrease in pressure ratio
C) It increases with decrease in clearance ratio
D) It decreases with increase in delivery pressure
Correct Answer: D
Solution :
\[{{\eta }_{v}}=1+c-c{{\left( \frac{{{p}_{2}}}{{{p}_{1}}} \right)}^{\frac{1}{n}}}=\frac{{{p}_{1}}{{T}_{0}}}{{{p}_{0}}{{T}_{1}}}\left[ 1+c-c{{\left( \frac{{{p}_{2}}}{{{p}_{1}}} \right)}^{\frac{1}{\eta }}} \right]\] \[{{\eta }_{v}}\] decreases as \[\left( \frac{{{p}_{2}}}{{{p}_{1}}} \right)\] ratio increases.You need to login to perform this action.
