O.K., I admit it, I played hookey from math class when they explained this.
I am trying to determine the formula for the speed of a pulley.
The crankshaft pulley is 6.25" diameter, and the pump pulley is 4.70" Diameter.
Assuming the main pulley to be turning at the following speeds, what speed would the pump be turning?
800 RPM
1600 RPM
3600 RPM
Many thanks in advance,
Tim
