if sec A-tan A = a/b
find the value of cos A.
I believe it is RPM's (Reps Per Minute)
To produce 60 hertz, a 2-pole generator must complete one full rotation for each cycle of alternating current. Since there are 60 cycles in one second, the generator must rotate 60 times per second. To convert this to rotations per minute, you multiply by 60, resulting in 3600 RPM (rotations per minute) for the generator.
4 km/per hour
Divide the litres per minute by 4.55
Multiply liters per minute by 0.0353146667 to get cubic feet per minute.

It depends on the wind and the rating for the windmill
1500 rotations per minute. That's crank speed.
Strokes per minute is not a unit of capacity and hence, there is no correspondence with gallons per minute. Strokes per minute is comparable with rotations or revolutions per minute. SPM is normally used for reciprocating machines, to define the speed. A. R. Pathak
Divide the litres per minute by 4.55
There is not a relationship without more information.
Multiply liters per minute by 0.0353146667 to get cubic feet per minute.
Cubic feet per minute x 28.3168 = liters per minute
Multiply meters per minute by 3.28 to get feet per minute.
