Determine increase in head loss for additional flowrate for pipe
(.. your note ..)
Total Headloss = Major Loss + Minor Loss
Increase = HL(after) - HL(before)
Determine impact on hydraulic grade for a circular pipe subject to additional flow
For example, consider
18 inch diameter pipe
300 feet length
n = 0.013
minor loss factor = 1
Total headloss for the pipe when carrying 10 cfs flow is 3.22 ft.
If 2 cfs is added to 10 cfs, the total headloss increases
by 1.42 ft resulting in (3.22 + 1.42) = 4.64 ft total head loss.
The table shows 1.42 feet as additional head loss.
