I'll elaborate more on my set-up. I have a an acrylic tube and inside the tube is a ball one side has a dC fan to output air and the other side is a small cover just to not let the ball escape from the tube when it levitates. My goal is measuring the pressure from below the ball(P1 = pressure at the front of the DC fan) and above the acrylic tube(P2 = pressure above the ball) basically the pressure difference in order to relate it with the Bernoulli equation and define how the ball levitates.
