Identify the 5 Friction loss laws
DRISL
Friction loss increases directly with the decrease in diameter
Friction loss increases with the roughness of the interior of the hose
Friction loss for all practical purposes, is independent of pressure
Friction loss increases directly as the square of the flow rate
Friction loss increases directly with the length of the hose
List the formula for calculating Head pressure
P = 10 x Height
If 700kpa is required at the branch at the end of two length of 38mm hose running up a 5m incline, what pressure would be required at the pump? Show calculations
