I thought I was using SI for the bulk of the equation and converting at the end but I wasn't sure I was doing it correctly.
I'm want to use PSI because I want to test the solution using a hydraulic press to experiment with different transom thicknesses in plywood.
I'm trying to calculate the maximum Force in PSI applied to the transom of a planing boat under acceleration using F=ma.
boat mass is 300kg
accelerates from 0 to 10m/s in 6 seconds
F=ma -> 500N = 300kg *(10m/s/6s) = 112.4045lbf
the contact area between the boat transom and motor is 1000 mm2 =...
I would like to calculate the values for an air curtain. I've tried using the aircurtain calculator from Engineering Toolbox:

Δp = 2.2 q2 sin(α) / b H3/4
but I'm not sure how to figure in the length of the opening - q (q =...
I had anticipated 80% efficiency in the belt drive system. I plan to drive two backward curved centrifugal fans. Will driving these types of fans be more more advantageous than driving another type of device?
Thanks for the responses. So the power stays constant, torque increases and speed decreases. So the two devices would have a max HP of 18 each (not accounting for drive train losses)? Is there a way to take advantage of the increase in torque at the device shafts?
I would like to drive two identical devices off of 1 power source. I would like to use two independent but equal sized V-belts, a double stacked pulley on the drive shaft and a single pulley on each of the device shafts. If the power source has a rating of 36HP @ 3600 RPM, what is the maximum...
