WebSep 15, 2024 · The statement that friction losses can be ignored on the suction side of NPSHa>NPSHr is false. Imagine a pressurized tank at 50 psig (static head + tank pressure), and line losses of 40 psig to the pump suction. The pump discharge head is 100 psig. NPSHr may be, say, 25 feet of water absolute. Though there is adequate NPSHa, it … Webthe pump has a rating of 10 gpm at 70 ft assuming that’s the flow rate we require the pump will produce 70 feet of head. This means that the static head must be less because a portion of the pump head is required to overcome friction. Therefore if the static head is close to the rated

WebThe total head is the sum of the static head (remember that the static head can be positive or negative) and the friction head. 5. Select the pump.
