Calculate fluid pressure loss due to hole leakage

  1. Feb 22, 2012 #1
    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?

    welcome to pf!

    hi raymond350! welcome to pf! :smile:

    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 :wink:
