Would a SWG be right for me?

I know its true but it doesn't even make sense.
My 1/2 horse motor uses 420W and i bet it doesn't move 22 gpm

Makes my brain wonder what a 30 hp motor turning 100 rpm uses.
I think @JamesW had a chart that showed efficiency of different sizes at different outputs but i can’t find it right now (JamesW apologies if I am mistaking you for someone else)
 
Based on the pump affinity law, the power is a cube factor of the ratio of the first speed divided by the second speed.

(3450/1725)^3 = 8

(3450/1000)^3 = 41

(3450/100)^3 = 41063.625

30 hp/41063.625 = 0.00073057359 hp = 0.545 watts.

But that is purely theoretical and not what would really happen as you have other factors that will cost power.
