I got a question that has been bugging me for quite a while and i cant seem to find the answer for it, and here it is...

If we have a pipe lets say 20" in diameter, with a flow rate of 1 m^3/sec at a pressure of 10 psi, and we get a pressure drop of 9 psi, is it possible to know the size of the hole in the pipe that is causing this pressure drop? and what is the volume of water that is being lost from said hole?

Thanks for the help...
