If the pipe is circular, you will find it according to the following equation: R = A / P = πr² / 2πr = r / 2 = d / 4. where r is the pipe radius, and d is the pipe diameter. You can view and modify all these parameters (area, perimeter, hydraulic radius) in the advanced mode of this pipe flow …
Note that at high flow rates the dynamic pressure at the hose bib often drops because of internal pressure losses in the water delivery system. The assumed C factor (internal to the equation constant) is 135 for flexible garden hoses. Water Flow Rate. Where: = Water flow rate from the end of the hose (gpm)

of 1/2" hose, at a flow rate of 10 gal./min., is 50 lbs./in.2 (0.5 x 100 = 50 lb./in.2). Hose Ends and Fluid Conveyed In most cases, the end fitting openings are slightly smaller than the hose itself. However, this varies widely with hose end designs from ‘full-flow’ ends which have the same I.D. as the hose, down to as much as 1/8"

54:(1.84 * 3600) = 65:(R * 1800) -or- R = 65 * 1.84 * 3600 / (54 * 1800) = 4.43 CIPR So, this "rule of thu" measurement puts the displacement at about 4.4 CIPR and 30.23 GPM flow: 4.4 * 0.97 * 1800 / 231 = 33.2 GPM Here is the case for a 7 HP engine running at 3600 RPM: 7:(1.84 * 3600) = 51:(R * 3600) -or- R = 7 * 1.84 / 54 = 0.238 CIPR
The hose I.D. must be sized accurately to obtain the proper flow velocity. A flow that’s too slow results in sluggish system performance and a flow that’s too high causes excessive pressure drops, system damage, and leaks. Use the Flow Capacity Nomogram to determine the proper hose I.D. for your appliion’s flow rate requirements.

27/9/2012· sired Flow of 10 Gallons per minute were known. The straight line intersecting the two known quantities intersects the Hose ID scale at 1/ 2". Therefore, a hose with 1/ 2" ID (-08) would be selected. * Gallons shown are Imperial (British) Gallons. To convert to US Liquid Gallons, multiply by 1.2009. Other Conversions: Gal/min (Brit) x 4.546 = l
All flow rates through hose other than 2 ½” must be converted to an equivalent flow as if it were flowing through 2 ½” hose. To calculate friction loss in various hose sizes other than 2 ½”, we have developed factors to convert the larger and smaller hose flows to GPM flow that creates the same amount of friction loss as in 2 W'' hose.
The desired flow rate must be between the minimum turnover rate and the maximum flow rate. The average of the minimum and maximum rates is the Desired Flow Rate. Minimum Flow (Turnover Rate) = 44 GPM Maximum Flow (Water Velocity) for 2” Pipe @ 6 FPS = 63 GPM Desired Flow Rate = 53.5 GPM Example 3 Page 8
