Calculating friction loss in hydraulic hose

02/16/2007 10:38 PM

Can anybody explain how to calculate friction loss in hydraulic hoses?

The appx. size I am considering uses 5/8" and 3/4" ID steel fittings

Pressure drop in pipes was evaluated by Osborne Reynolds in the 1870s-1880s.

http://en.wikipedia.org/wiki/Reynolds_Number will help.

Dear Mr.DK Lost in Michigan,,

The Head Loss Formula is H = (4 x f x L x V^2)/(2 x g x D)

Where H = Head Loss in Ft., f = Friction Co-Eff., L = Length of pipe Feet, V = Velocity of Fluid in Feet, g = Acceleration due to Gravity, D = Dia of pipe in Ft.

The Velocity can be calculated once you know the Flow Rate and Pipe Dia.

Pl. refer any standard Hydraulics Text Book preferably by E.H.LEWITT,
