Water System Planning: Estimating Water Needs For a well, the yield is considered the maximum rate in gallons per minute (GPM) that a well can be pumped without lowering the water level in the borehole below the pump intake. For most single-family homes, a minimum flow of 6 GPM is suggested from a well or spring.

Pump Flow Pump Parameters. Pump operation and performance can best be described by a few fundamental parameters; flow rate, pressure, head, power, and efficiency. Volume flow rate (Q), also referred to as capacity, is the volume of liquid that travels through the pump in a given time (measured in gallons per minute or gpm).

Chapter 7 Fire Hose Nozzles and Flow rates What are Constant Flow Nozzles? Designed to flow a specific amount of water at a specific nozzle discharge pressure on all stream patterns. Most constant flow nozzles are intended to be operated at a nozzle pressure of? 100 psi, although there are some lower pressure nozzles that operate at 50 to 75 psi.

Water Pump Buying Guide When shopping for a water pump there are various items to consider. All water pumps are measured in discharge capacity (GPM), vertical suction lift, and maximum head lift. GPM Discharge Capacity is the rate of speed that water flows from the source to the discharge point, measured in gallons per minute. It provides the power to move water quickly.

- Your well pump can pump water up to a certain maximum flow rate, in gallons per minute. For example say you could fill a 5 gallon in 1 minute. This is a flow rate of 5 gallons per minute or 5 GPM. If the water filled up a 5 gallon bucket in 30 seconds, the flow rate would 10 GPM.

- Future flow through the force main (as determined by the Water and. Wastewater Engineering Division) is less than 200 ERU (120 gpm peak flow). If a 4-inch force main is allowed, pumps will be sized to deliver the peak flow or 100. gpm, whichever is greater, in order to have at least 2.5 fps velocity in the force main.

Pump Flow The pump curve illustrates the available total head at a given flow rate of the pump. Generally, more head is available in the pump as flow rate decreases. Manufacturers usually designate an optimum or best efficiency point (BEP) of the curve, which is indicated in this graph by the dotted line.

- The overall efficiency of a centrifugal pump is simply the ratio of the water (output). power to the shaft (input) power and is illustrated by the equation below. η = P W / P S where η is efficiency, P w is the water power, and P s is the shaft power. In the US, P s is the power provided to the pump shaft in brake horsepower and P w is P w = (Q x H) / 3960 where Q is flow in GPM and H is head in feet. The constant, 3960, converts the product of flow and head (foot‐pounds or the more politically correct term pound‐feet) into BHP.

- The higher the flow rate, the higher the pressure will be for a given plumbing system. The larger the pump HP, the higher the flow rate and thus the higher the pressure will be. 17-20 PSI is not unusual by any means for a pool. I run at about 19 PSI with a 1 HP Northstar pump (SF = 1.85), 2 1/2 suction plumbing and 2 return plumbing. With the solar system on, the pressure rises to about 27 PSI.
