The pressure drop across an orifice is measured for a particular flow rate. If the flow rate is doubled, keeping all other parameters constant, the effect on the pressure drop across the orifice is.

It will remain same

It will also be doubled

It will be halved

It will increases by four times

$Q\propto \sqrt{\Delta P}\phantom{\rule{0ex}{0ex}}\frac{{Q}_{1}}{{Q}_{2}}=\sqrt{\frac{\Delta {P}_{1}}{\Delta {P}_{2}}}\phantom{\rule{0ex}{0ex}}(\frac{{Q}_{1}}{{Q}_{2}}{)}^{2}=\frac{\Delta {P}_{1}}{\Delta {P}_{2}}\phantom{\rule{0ex}{0ex}}\Delta {P}_{2}=\Delta {P}_{1}(\frac{{Q}_{1}}{{Q}_{2}}{)}^{2}\phantom{\rule{0ex}{0ex}}\because {Q}_{2}=2{Q}_{1}\phantom{\rule{0ex}{0ex}}\Delta {P}_{2}=\Delta {P}_{1}(\frac{2{Q}_{1}}{{Q}_{1}}{)}^{2}\phantom{\rule{0ex}{0ex}}\Delta {P}_{2}=4\Delta {P}_{1}$

So answer is it will increases by four times.
