I have a pressure washer that is rated for 1.4 GPM and 2000 psi. The hose's diameter is 4mm.

I want more GPM and ok with less psi. Would getting a bigger nozzle automatically give more GPM but less psi?

Is this the correct formula to use?

Flow rate = 1.4 GPM x 2000 psi,
flow rate is 2,800 (GPM x psi),

The new psi is 2,800 / 2, and therefore psi is 1400.

I think I did something wrong. It cannot be this simple, right? I think Bernoulli's equation only applies if the output diameter stays the same, but I want to increase the diameter to get more water out but ok with less psi.

Max flow rate is limited by the max RPM of the motor.

PS. that probably is far higher than twice the normal speed

Power = pressure * volume (ignoring pump's limitations)

Yeah, that's how I know some of the equation. I figured I would check in with people who actually know stuff.

I think this person answered it >>16243366
