1 Barrel = 42 gallons

Gallons Per Minute = Barrels Per Day × .0292
GPM = BPD × .0292

Horsepower = Torque in Inch Pounds × (Revolutions Per Minute) ÷ 63,025
HP = ((Torque in Inch Pounds) × RPM) ÷ 63,025

1 US Liquid Gallon = 231 Cubic Inches
1 US Liquid Gallon = 231 Inches^3

1 US Liquid Gallon = 0.13368 Cubic Feet
1 US Liquid Gallon = 0.13368 Feet^3
