Calculate fluid pressure loss due to hole leakage

[raymond350]

I have a cylindrical pipe of internal diameter of around 5mm, say capped at one end with pressurised fluid flowing though the other opening. If I have holes at the wall of the pipe, am i able to calculate the pressure loss due to water squirting out through those side holes?

hi raymond350! welcome to pf!

if it's capped at the end, why should there be any pressure loss?

if the water supply is from a constant-head tank, then the pressure will stay the same

if it's from a tank that isn't being refilled, then the loss of pressure will depend on the horizontal area of the tank … the faster the water goes down, the greater the loss in pressure
