Pressure drop in pipe fittings and valves | equivalent …

If the piping were smooth HDPE with a roughness of 0.0002" the pressure drop in the pipe would be only 1.89 psi per 100 ft and the length of HDPE piping that would give an equivalent pressure drop to the valve would be 108 ft, giving an L e /D ratio of 420.

Darcy–Weisbach equation - Wikipedia

The friction factor f D is not a constant: it depends on such things as the characteristics of the pipe (diameter D and roughness height ε), the characteristics of the fluid (its kinematic viscosity ν [nu]), and the velocity of the fluid flow v .It has been measured to high accuracy within certain flow regimes and may be evaluated by the use of various empirical relations, or it may be read

Some Friction Loss Tables

Example: Determine L (friction loss in pipe fittings in terms of equivalent length in feet of straight pipe). Assume a 6" angle valve for Schedule 40 pipe size. Select the appropriate K value for such and select D and f for Schedule 40 pipe from the table below where K is the pipe diameter in feet.
