Friction Loss Velocity Table (Schedule 40 pipe)

Friction Loss Velocity Table (Schedule 40 pipe) For steam system to work properly,it is important to maintain reasonable velocities of liquid passing through piping.Pipe velocities are a function of gallons per minute and pipe diameter.Pipe diameters are selected to achieve a velocity of 5-10 feet per second.Guidelines for using tables:Hazen Williams vs Moody Friction Factor Pipeline Pressure Sep 19,2017·The relative roughness of new steel pipe can be calculated as; /D = (0.0002 ft / 6.065 in)(12 in/ft) /D = 0.0004.Considering the Re of 5.2 x 10 5 and relative roughness of 0.0004,we arrive at a friction factor of 0.017 approximately.The head loss due to friction can be determined as follows; Hf = fHazen-Williams Coefficients Table Engineers Edge www fluid flow.Hazen-Williams Coefficients Table .Fluids Flow Engineering Hydraulic Pneumatic Design Engineering,.Hazen-Williams Coefficients Table.The HazenWilliams equation has the advantage that the coefficient C is not a function of the Reynolds number ,but it has the disadvantage that it is only valid for water .Also,it does not account for the temperature or viscosity of the water.
