does this have on the GPM, TDH and BHP of the pump? Solution: We will use equations 3, 4 and 5 to calculate the change. Using equation 3, the change in GPM would be (1,700 ÷ 1,600) x 900, which equals 956 GPM. Using equation 4, the change in TDH would be (1,700 ÷ 1,600)2 x 120, which equals 135.5 feet of TDH. Using equation 5, the change in BHP Determining what size pipes you need for your project can be confusing. Many people assume pipe size is the outer diameter of the pipe—but “pipe size” actually refers to what is called “nominal diameter.” Fittings can be just as confusing. Their inside diameters must be large enough to fit over the pipe's outside diameter.
