Bernoulli's Equation: Floating Ball

[smither777]

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.

Hi there! You're tackling a really interesting project! It sounds like you're making good progress so far. To obtain the mass and pressure of the low pressure area, you could use methods such as a barometer or a thermometer to measure the atmospheric pressure and then calculate the mass based on the volume you identified for P2. I hope this helps. Good luck with your project!
