Belt size

I need to know what size v belt i need to drive only the water pump on a sbc. The water pump is broken where the ps pump bolts to it so i have it bolted trough the hole with a nut on the backside; it holds it fine but i cant adjust the belt tension for the ps pump. So i want to connect the crank to the water pump with one belt and then have the alternator and ps pump on the other belt driven by the water pump. So what size belt do i need to connect the crank and water pump only? Thanks

The PS pump pulley doesnt line up on the same plane as the alternator.......

If you want to measure how long of a belt you need for something, take a piece of 3/8 rope and wrap it around the pulleys that you want the belt on.......mark how long you need and measure it. Chances are you are not going to find one the exact length you need....thats why you need adjustment for belts
