Thats why i asked. I believe a electric motor will be more consistent and put out a steady HP. The more i thought about it the more questions i had lol. I feel like if you put a 5 hp electric motor against a 8 hp gas that it would be a close match.
The formula is what I posted from cat pumps webpage but you input your pump RPM in the division portion.
I will send you some pics if I can find my motor data book. It’s somewhere around here. Or search online for electric motor reference data book. Might find all the info.
My book has formulas for determining HP, RPM, Torque, Load, Shaft torque, ratings duty cycles etc.
my oilfield data book just gives the basic HP formula. Which I posted

5hp electric is equal to a bit more than 10hp gas

9.6hp on a gas engine
Why the difference in hp rating between gas and electric? Just the way the power is delivered? You would think 10hp would be 10hp.
I have a 5 hp Baldor on my air compressor and that motor is a heavy beast for its size. It had a 3 phase motor on it when I bought it so ordered the Baldor and sold it.

@marinegrunt Torque is what does the work, hp will keep you there. Electric motors are torque monsters, gas engines don’t quite excel in that department. If you want to drive a PW pump with a diesel Kubota engine you’ll be closer to what a electric motor can do hp for hp.

Kind of like a 250cc crotch rocket will blow a Harley 1300cc bike out of the water? Lol
I don’t do bikes but I’d imagine that has more to do with the horsepower to weight ratio
Nah its a torque thing too.
I’m challenging that but I’m too tired to look up their specs. You win by default
