Pressure Loss in Hoses | Neutrium

Rubber hoses may also be reinforced with woven fabrics, however this does not effect the flow properties of the hose. Pressure loss through Straight Hose The pressure loss through a straight hose is directly proportional to the length of the hose, therefore the simplest method to quantify the pressure loss is to substitute the length of steel pipe required to provide an equivalent pressure drop.

Pipe Roughness - Pipe Flow Software

The roughness value, usually denoted as e, is used in the calculating the relative roughness of a pipe against the size of its diameter. Absolute Roughness The roughness of a pipe is normally specified in either mm or inches and common values range from 0.0015 mm for PVC pipes through to 3.0 mm for rough concrete pipes.
