PS = suction pressure, psia. Pd = discharge pressure, psia. SG = specific gravity. Vs = suction velocity, ft/s. WebMar 8, 2016 · Total of 60.4 added equivalent feet of straight pipe. To convert this value to feet of head, multiply 60.4 ‘ by the same number used in the length of pipe calculation above for 70 GPM and 2’ PVC diameter pipe, 7.76 per 100’ of pipe. 60.4 / 100 x 7.76 = 4.69. Total of 4.69 added feet of head for connectors.
WebTotal head = static head + friction losses + pump head where the static head is the difference in elevation between reservoirs A and B, and pump head is the additional head required to overcome losses in the pump and any other fittings. Static head = 220.0 ft - 50.0 ft = 170.0 ft Next, we need to calculate the friction losses in the pipe. WebThe performance of the pump at a certain speed (RPM) can be found in the manufacturer’s datasheet displayed as the flow rate (Q) versus head curve (figure 2). At the maximum …
