if sec A-tan A = a/b
find the value of cos A.
I believe it is RPM's (Reps Per Minute)
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.
-- to convert the feet to inches, multiply by 12-- to convert the minute to second, divide by 60-- combining these operations, take (feet per minute) and multiply by (12/60) = 0.2
Revolutions Per Minute Rotations Per Minute
I believe it is RPM's (Reps Per Minute)
4 km/per hour
1500 rotations per minute. That's crank speed.
It depends on the wind and the rating for the windmill
Divide the litres per minute by 4.55
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
Cubic feet per minute x 28.3168 = liters per minute
Multiply liters per minute by 0.0353146667 to get cubic feet per minute.
There is not a relationship without more information.
Multiply meters per minute by 3.28 to get feet per minute.
-- to convert the feet to inches, multiply by 12-- to convert the minute to second, divide by 60-- combining these operations, take (feet per minute) and multiply by (12/60) = 0.2
