Let

$p_1$ and $p_2$= Pressure at inlet and exit respectively;

$v_1$ and $v_2$= Velocity at inlet and exit respectively;

$A_1$ and $A_2$= Area at inlet and exit respectively;

n = adiabatic index;

ṁ = mass flow rate or discharge

$\frac{ṁ}{A_2} = \sqrt{\Bigg[2\Big(\frac{n}{n-1}\Big)\frac{p_1}{v_1}\bigg\{\Big(\frac{p_2}{p_1}\Big)^{\frac{2}{n}}- \Big(\frac{p_2}{p_1}\Big)^{\frac{n+1}{2}}\bigg\}\Bigg]}$

On substituting the condition of maximum discharge, …
