Water flows in a horizontal pipe whose one end is closed with a valve. The reading of the pressure gauge attached to the pipe is $\displaystyle \mathrm{P}_1$. The reading of the pressure gauge falls to $\displaystyle \mathrm{P}_2$ when the valve is opened. The speed of water flowing in the pipe is proportional to
