Re: RPM Formula

[acfm]

I seem to be missing my Dayco Power Transmission Book! Can someone please provide me with the formula for determining rpm's based on the sizes of the motor, belts, bushings and sheaves? I currently have an old pump system with no informataion associated with it?

Thanks!

HP = pump speed cubed

HP2/HP1 = (RPM2/RPM1)^3

1. Motor pulley Dia. = Driven pulley dia.x RPM ^ Motor RPM

2. Belt length = (D x 1.5708)+ 2 times center to center distance D = large pulley dia. + small pulley dia.
