Hi, I'm doing a project - Bernoulli's floating ball and i am trying to explain it using bernoulli's equation: P1 + 1/2pv1^2 = P2 + 1/2pv2^2 Where P1 represents the High pressure areas surrounding the jet air and the ball (atmospheric pressure) of which I have managed to obtain its variables. It is the low pressure area (P2) which I have a problem with. I believe I can obtain the volume (for p) by presenting an orientation of which is a cylinder, but I don't know how to obtain mass and the Pressure itself. I will use the equation to obtain the velocity (v2) at the low pressure area. Can anybody help? Thanks.
