Get Jetting With Jonesie - Hose Pressure-Drop Comparison

Get Jetting with Jonesie - Pressure Drop Comparison:

In this segment of "Get Jetting with Jonesie", Steve Jones takes us through a comparison of the Pressure-Drop seen thru 300-feet of 1/4"(.25"I.D.) vs. 300-feet of 5/16"(.31"I.D.) Jetting Hoses. The result is a dramatic 45% difference in net GPM/PSI performance, with only a 1/16"(.06") 20% net difference in hose I.D. (Inside-Diameter). Note also that both hoses are run using the same 8-GPM Warthog 1/4" Nozzle, and both hoses are fed by the same 9gpm/4000psi Jetting-System. The comparison results:

(a) 300-feet of 1/4" (.25"I.D.) Jetter-Hose: net 6-GPM at 2100-PSI (12,600 C.U.)
(b) 300-feet of 5/16"(.31"I.D.)Jetter-Hose: net 7-GPM at 3300-PSI (23,100 C.U.)

C.U. = "Cleaning Units" of Power (GPM x PSI = CU)
