You would use the ratio we discovered in our last step (0.611) to figure out what size pulley you would need on your pump. With a ratio of 0.611, and a 4-inch pulley on your motor, you would need a 6.55-inch pulley on your pump. Broken down into a math problem, this looks like: 4 inches / 0.611 = 6.55 inches
