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!!!
