Conversion Factors

1 inch = 25.4mm 1 gal H20 = 8.33lbs 1 gal = 3.79 liter 1 kg =2.205 lbs
1 cm =0.394 inch 1 oz = 23.35 gram 1 liter = 0.2642 gal 1 KW = 1.341 HP

Horsepower (HP) Equations

HP = GPM x PSI PSI = HP x 1460 GPM = HP x 1460
1460 GPM PSI

Pulley Equations: Pump Pulley diameter x Pump RPM = Manufacturer Pulley Diameter x Manufacturer RPM.

Q: How fast do I turn my pump to give me a desired GPM?
A: Required RPM = (desired GPM x Rated RPM)
  Rated GPM
Q: What size pump pulley do I use to get a certain RPM?
A: Pump Pulley Diameter = Motor Pullye Diameter x Motor RPM
  Pump RPM
