If your rpm is 580 at the water pump pulley and the water pump pulley has a 20 % smaller diameter than the crank shaft then D water pump/ Dcrankshaft = 0.8. Your crankshaft speed is 580/0.8 =725 rpm. The equation is N1 x D1 = N2 x D2 = a constant. So knowing one rpm and the diameter of the respective pulleys, or the diameter ratio of the pullies, you can calculate the other desired rpm
