(OP)
how do i calculate the theoretical amp draw on a motor for a specific centrifugal pump. I know the pressure drip across, viscosity,....

RE: Calculating amp draw on a centrifical pump
SeanB's answer is correct in methodology but the electrical power calculation is probably incorrect (unless you happen to have a DC motor driving your pump).
The methodology described mentions the pump efficiency (f you have the curves, use them). Motor efficiency also needs to be taken into account.
The formula I have for electric horsepower is:
P= volts x amps x power factor x 1.73 / 746 for 3-phase. You drop the 1.73 for single phase.
