Thank you mfb for your help. I think my calculation for velocity of sinking bubble without flow should be correct. But then as you said when there is a flow the flow velocity changes in different cross section of tunnel. I draw a basic sketch of tunnel and the rectangle in the sketch is the...

well, first I want to calculate the maximum flow velocity in my system to figure out required pump. I am not sure how to calculate the flow velocity based on the shape of the tunnel and the sinking rate of bubble.

Sorry, I think I didn't explain the problem very well. I am trying to determine the the flow velocity in a way that can stabilize a sinking bubble in a tunnel. (Tunnel is tapered and the size is fixed)

Hello, I am trying to find the required flow rate for stabilization of a bubble (to control the sinking and rising of bubble) in the water tunnel. I found the velocity of sinking bubble in the water (when the flow rate is zero) but I am not sure how to use that to find flow rate of my system to...
