To choose the proper diameter of the hose, you need to know total flow rate (gpm) that will flow through the hose in order to calculate “friction loss”. In this curve, head is measured in PSI; flow is measured in gallons per hour. To calculate the jet velocity and flowrate, enter the parameters below. , according to the System Syzer. Below is a sample shot of the spreadsheet. For example, a pump with a flow rate of 12 GPM doesn't mean that it can't provide a household with 15 GPM, it just means that the pump is most efficient at 12 GPM. For example, a 008 pump can produce almost 8 ft of head at 10 gpm flow rate. There are two main factors in GPM calculations: 1. Submersible water pumps are designed to operate in a specific operating range of how much capacity they will pump while overcoming the total dynamic head pressure (TDH) of the discharge system. Example: The output flow of a pump spinning at a rate of 2000rpm with a displacement of 2. Factors Affecting Head-Discharge Curves Many factors affect the pump head-discharge curves measured, including the design of the pump and the size of the pump and power unit. If you have a 20 gpm pump set at say 1000 psi then open a valve fully somewhere down stream, the pressure will fall until the friction inside the piping is great enough to create some pressure by resistance to flow. The power needed to drive a reciprocating pump depends on the maximum pressure, pump capacity and mechanical efficiency of the pump. Determining the gallons per minute: 24,000 gallons ÷ 8 = 3,000 ÷ 60 = 50 GPM (gallons per minute) Check the Plumbing Flow Rate. The energy requirement increases with every foot the water is lifted. 50 Immersion Depth (Decimal Inch) 7. For example if sprinkler requirement is 250 gpm and hose demand is 250 gpm our fire pump size will be 500 gpm rated capacity. Figure 1 is an example of a PRV controlled constant pressure booster.
