I am tasked to design an orifice plate to be inserted into a water tunnel in an experiment. I am having some problem with the force calculation.(adsbygoogle = window.adsbygoogle || []).push({});

To understand the amount of pressure being applied onto the plate, the dimensions of the orifice is known. P = F/A

A is known therefore I need to calculate what is F.

F = ma

I am not sure can I use m = density x area x velocity

If it is correct, how do I determine what is the acceleration?

Once the velocity of the water is being regulated and remain constant, it will means that the acceleration is = 0.

Will need some help here. Thanks alot!
