First principle of friction loss
If all other conditions are the same, friction loss varies directly with the lenght of hose or pipe.
Second principle of friction loss
When hoses are the same size, friction loss varies with the square of the increase in the velocity of flow.
Third principle of friction loss
For the same discharge, friction loss varies inversely as the fifth power of the diameter of the hose.
Fourth principle of friction loss
For a given flow velocity, friciton loss is approximately the same, regardless of the pressure on the water.
Water is incompressible-
For that reason the the same volume of water supplied to one end of a hose under pressure, the smae amount will come out the other end
