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.
