Gallons per minute can also be calculated by multiplying the horsepower by 1,714 and dividing the product by the fluid pressure. For fluid motor torque, the formula is the torque times the rotations per minute, divided by 36.77 times the pressure. Pump output flow in terms of gallons per minute can be found by multiplying the speed in rotations per minute by the displacement in cubic inches divided by 231.
