The pressure loss is based on the actual ID of the hose. Pressure loss is typically stated as "head loss in feet" to better account for elevation changes. Using the stated nominal hose size the pressure loss is as follows:
Head Loss:
5/8" ID hose = 4.56 Ft/100Ft @ 2 GPM and 24.8 Ft/100 Ft @ 5 GPM
3/4" ID hose = 1.93 Ft/100Ft @ 2 GPM and 10.5 Ft/100 Ft @ 5 GPM
1 1/4" ID pipe = .862 Ft/100Ft @ 5 GPM and 3.12 Ft/100 Ft @ 10 GPM
The above data is the head loss due to friction between the water and the hose that the pump must overcome. Elevation changes must be accounted for by adding to (uphill) or subtracting from (downhill) the friction loss.
For example: Assume you want at least 2 GPM, have a 10 foot increase in elevation, 300 feet of 5/8" hose and 400 feet of 3/4" hose. The friction loss would be [3 x 4.56] + [4 x 1.93] + 10 = 31.4 Ft. To convert to Psi we divide by 2.31 resulting in a pressure loss of 13.6 Psi. If your pump output is greater than 13.6 Psi then the flow rate will increase until the friction loss +/- elvation change equals the pump output.

Today's Featured Article - The 8N and the Fox - by Zane Sherman. Dec. 13 1998, Renfroe, Alabama. Last niht I dreamed about the day that I plowed the field of about 10 acres over on what Jimmy and Dandy called the Ledbetter field. I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
