WebHead Height Help. The head height rating and maximum lift are important in sizing a fountain pump. To do this, first, measure the diameter of the fountain spout. Multiply that number by 100. This calculates the gallons per hour – or GPH. If the fountain spout is 2 inches in diameter, then the fountain has 200 gallons per hour – or 2 x 200 ... WebMay 28, 2024 · To calculate friction loss, divide the total length of pipe by 100 and multiply it by the friction loss factor. For example, 40 gpm through 290 feet of 2-inch pipe will result …

Web1) Flow Rate - the gallons per hour of water that is flowing through the pumping system. 2) Pipe Length - the total length of PVC pipe used to plumb the pond. 3) Static Head - the height of the waterfall or water return above the pond surface. ie. a 5' waterfall will have a static head of 5'. 4) Diameter of Pipe - the size of schedule 40 PVC ... WebHere are the simple and easy steps to calculate the water pressure. Take the height of the outlet from the base. The formula to compute the water pressure is P = ρ * g * h. Where ρ is the density of water, g is the gravitational constant and h is the height. The constant value of water density is 997 kg/m³, gravitational constant is 9.81 m s -2. WebJan 18, 2024 · The following formula is used to calculate a Condenser Pump Head. CPH = (p2-p1)/p*g + (c2-c1)/2*g+(z2-z1) Where CPH is the Condenser Pump Head (m) ... For this pump, the height difference is 1m. Next, determine the density of the fluid. This pump is running water, so the density is 1.225 kg/m^3. incorporated village of hempstead water
