I am seeking a general answer relative to boat speed and psi effect on a transducer. I understand many variables affect this, ie, salinity, current, etc. Assuming a transducer mounted on the back of a boat hangs below into the water 1/4", water forces increase against this object as boat speed increases. The transducer is purposely 'egg-shaped" and mounted longitudinally to reduce drag. I am seeking round-about psi water force on the face surface of the transducer of approximately 2" sq (max), in 10 mph increments from 10 to 80mph. I am looking for a backup theory to assist in substantiating what I now believe to be somewhat accurate. There is likely no way to compute accurately, but close is workable. I am not schooled in physics, so, the simpler the better. Thanks!!!

What kind of transducer are you referring to? What is the purpose of the transducer? Without an exact shape, the only quick and dirty way to calculate the forces acting on that would be to simulate it as a flat plate which will give you higher forces and thus be inaccurate.

The shape is commonly elliptical, to facilitate lessening drag. I believe I likened it to an "egg'shape". Just picture maybe 1/4 of an egg below the bottom at the stern of a boat dragging in the water 1/4" below the bottom. The 'egg" (or transducer) would be positioned where the ergonomic ends would point fore and aft. It could be any kind of transducer for sonar, or camera, or maybe microphone, but would trail behind a boat at float or at a faster speed as I have indicated. Thanks!
