The easiest way would be to capture the sprinkler water and fill a 5gallon bucket and time your self. When the buckets full then divide the time it took by 5 and you have your GPM.

Flow rate in GPM (Gallons per Minute) can be computed using a water meter. One can also use a vessel of fixed capacity, let fluid flow in and measure how much time it takes to fill up.

How do you calculate horse power of compressor?

To calculate the horse power of a compressor one would need to use the following calculation. Pump ratio x GPM @ 100 psi = CFM. For a gas compressor divide CFM by 2 and for an electric compressor, divide CFM by 4. GPM is gallons per minute and CFM is air consumption in cubic feet per minute.


What flow rate is required for an infinity edge swimming pool of 35 feet?

It doesn't make any difference how many sides of the pool are negative edge, only the total number of linear feet of negative edge and how level you can make the edge. The longer the edge the more important it is that it be level, because even small amounts of out of level require huge flow rates to compensate for. Approximate GPM required per linear foot for various water depths: 1/8" - 5 gpm ¼" - 10 gpm ½" - 17 gpm ¾" - 28 gpm 1" - 40 gpm 1.5" - 70 gpm 2" - 105 gpm As a minimum 5x35=175 GPM
