A Output pressure formula for a pressurized waterjet

  1. May 20, 2016 #1
    Hello,

    We have a pressurized Water-jet stream, where the nozzle d= 0.8 mm. We can measure the fluid output in mm3/s, to determine the speed by dividing over the area.

    For this, F=ρAv2

    However, the variable that would be changing, would be the distance from the nozzle to the target. If we assume that as long as the water-jet stream maintains coherence, A1=A2, therefore cancelling A for P=F/A, would the simplified formula:
    P=ρv2

    Be correct (if we do not want to be overly particular of effects that might not alter this formula in a significant way)?

    Thanks,
    Adbury
