how many gallons per minute does a 10 hp pump?
I need help in computing the Galons per minute pumped by my Century A.O. This flow chart will tell you how many gallons per minute or per hour the pump will give you for every foot of lift the pump can push up until its maximum head. Horsepower Required to Drive a Pump.

that will be determined by the GPM Gallon Per Minute rating of the pump. Because of this, most building codes set maximum flow rates of 8 feet per second through copper pipe and 10 feet per second through PVC. Most 1/3 horsepower sump and effluent pumps will deliver between 35 and 50 gallons per minute at 10 feet of vertical lift or total dynamic head. In order to determine how many heads you can use per zone, you need to know your water pressure and flow rate. How many gallons per minute or gallons per hour does a 3/4 hp pump when running without any restrictions. Example: The input horsepower required for a pump that needs to provide 10 GPM at 2000 psi is: HP= (10 x 2000) / 1714. Gallons per minute (GPM) Pounds/Sq Inch (PSI) Horsepower; Example: How many horsepower are needed to drive a 5 gpm pump at 1500 psi? Formula: GPM x PSI x .0007 = horsepower needed Find the water pump's gallon per minute (GPM) capacity as stated in the manufacturers specifications. Wayne WLS200 can pump the water up to 4310 Gallons Per Hour at 30 psi and at 10 feet. Flow = Gallons Per Minute. It features 2 horsepower maximum flow rate when the motor is factory set to 240 Volts. Measure the vertical distance between the water level in the base reservoir tank and the water input at the destination tank and write down the measurement in feet. If you want to run the pump less you will need to increase chlorine output on the chlorine generator. Skimmer1=50' Skimmer2=50' Main Drain = 56' Average Head = 52' At different pressures, the sprinkler head and nozzle will consume different amounts of water. Pressure = Pounds per Square Inch . Unfortunately, recommendations aren't that straightforward because you also need to account for water pressure, material friction and more. Disc. Completing the sample problem you have 3.0 gallons divided by 2.8 minutes which equals a pump rate of 1.1 gallons per minute. I got 2 to 3 gallons per minute. The rate is that it should be able to cycle the total volume of the pool in 8 hours. Since heaters all use copper heat exchangers, use 8 feet per second even if the plumbing is PVC. Once the pump is working, measure how many gallons per minute are being pumped and estimate the horsepower based on these values. Total Gallons Turnover Hours 60 Minutes = Minimum Turnover Rate Gallons 6 Hour Turnover 8 Hour Turnover 10 Hour Turnover 15,000 50 GPM 31 GPM 25 GPM 20,000 67 GPM 42 GPM 34 GPM 25,000 83 GPM 52 GPM 42 GPM 30,000 100 GPM 63 GPM 50 GPM Example 2 21,120 Gallons 8 Hours (assumed) 60 Minutes = 44 GPM Minimum Turnover Rate Page 7
Let's say you measured your pump and know it pumps 100 gallons per minute at 1,000 RPM. Smith B858 56Y Square Flange 1-1/2 HP Full Rated Pool and Spa Pump Motor. Los Angeles County, for example, allows a maximum flow rate of 8 feet per second on suction pipes of any type. We regularly get asked about the water flow capacity of different pipe sizes, and which is the best roof drain for a specific pipe size. How much water can flow through a pipe (GPM/GPH)? As an example a 1 horsepower (hp) pump is rated for 20 GPM, but is only able to deliver 10 GPM of water from the well source. I wasn't happy with it so coughed up another 1500 dollars to have it hydro-fractured. I have two skimmers and a main drain. The ratio is 1 gallon for every 10 RPM, or 1:10. 10.5 2400 1500 600 VS PlusHP Pump Gallons Per Minute Turnover Rate Model THP*** Amps 230V RPM 20 40 60 80 100 120 140 160 180 200 220 240 260 FEET OF HEAD TDH 6 hr 8 hr Suc. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). A two-line jet pump can typically raise water from depths of 30-feet to 80-feet, and at water delivery rates of 4 gpm (gallons per minute) (for a 1/2 hp 2-line jet pump serving an 80 foot deep well) to 16 gpm (for a 1 hp 2-line jet pump serving a 30 foot deep well).

There are 1/3 horsepower effluent pumps that will pump 60 gallons per minute at a 10 foot total dynamic head. 16,200 gallons x 2 turnovers a day = 32,400 gallons per day; 32,400 ÷ 24 hours = 1,350 gallons per hour; 1,350 ÷ 60 minutes = 22.5 gallons per minute - GPM; We can see that a 16,200 gallon pool run 24 hours a day requires 22.5 GPM output. When I did that some rock shifted and I could only lower the pump to 126 feet where I got a flow of 5 gallons a minute but only for 45 minutes before the pump started to suck air. Continued down to a total of 220 feet. If we use the example above that your waterfall is needing 108 gallons per minute, and your waterfall is 7 feet tall, you will need a pump that can produce a flow of 108 gallons per minute at 7 feet. Now if you measure the pump's output and find it has pumped 2.3 gallons in one minute, you can estimate its RPM is 2,300. It is designed to operate underground sprinkling systems, draw water from wells, lakes, or ponds for watering, to fill the swimming pool or any other applications where high water volume is needed. You can find your own pumps capacity without the specifications. Turn on the pump and a stopwatch at the same time.
