Pressure drop in pipe fittings and valves | equivalent

In long pipelines most of the pressure drop is due to the friction in the straight pipe, and the pressure drop caused by the fittings and valves is termed the "minor loss". As pipes get shorter and more complied the proportion of the losses due to the fittings and valves gets larger, but by convention are still called the "minor losses".

PVC Resistance Coefficient, K - Pipelines, Piping and

Dec 06, 2004· This is sometimes confusing when using the Crane 410 procedures. The way Crane correlates the K value it does seem to be affected by the friction factor - but this is just a "standard" friction factor that Crane have chosen to use and it has nothing to do with the actual friction factor (or pipe roughness) of the actual material.

K Factor For Reducer And Friction Factor For Material

Feb 28, 2012· K Factor For Reducer And Friction Factor For Material Other Than Steel - posted in Industrial Professionals: Dear Forum Meers,For calculating the K factor for a reducer/ expander and friction factor for materials other than steel, I have below two questions: For any reducer, Crane TP-410 says that the K value is independent of size ie. It doesn’t depend on the friction factor.

Pipe Fittings - Pluing - Grainger Industrial Supply

Find fittings, connectors, joints and joiners you need to attach, join and lengthen pipes. Elbows and tee joints ared used mostly with cold water, waste pipe and drain appliions. Steel fittings are used with air, water, oil, natural gas and steam.

Appendix A: Friction Losses for Water Flow Through Pipe

pipe uses a C value of 140, but with use and corrosion a lower value is typically used. For HDPE pipe, a range of C values between 150 and 160 is typical. Tables A.1 and A.2 show friction loss data calculated by the Hazen Williams formula for the most commonly used steel and PVC pipe diameters, based on C values of 140 and 150, respectively.

Re: Custom K factor calculation for pipe fittings. Hi Jeremy thanks for your reply, I have been working with js1900 on this. We had looked through those calculations in Revit help which are well explained for pipes.

The Performance Pipe

DR = OD Controlled Pipe Dimension Ratio . t OD DR = OD = OD-Controlled Pipe Outside Diameter, in. t = Pipe Minimum Wall Thickness, in. The dimension ratio, DR, is the ratio of the wall thickness to the pipe outside diameter. The lower the DR, the thicker the pipe wall, which correlates to a higher pressure rating. Two design factors, A f and f T
