Valves and Strainers Friction Head-Loss. Pressure drop in valves and strainers is calculated using flow coefficient values, How do you calculate pressure loss from fittings?How do you calculate pressure loss from fittings?There are several other methods for calculating pressure loss from fittings, such as The Velocity head method is named as such because it represents the pressure loss through a fitting as the equivalent number of velocity heads. It is in some ways similar to the equivalent length method, and the two may be equated by the formula below:Pressure Loss from Fittings - Excess Head (K) Method pipe fitting loss coefficients professional supplier What is a pipe fitting?What is a pipe fitting?Fittings such as elbows, tees, valves and reducers represent a significant component of the pressure loss in most pipe systems.

What is fitting loss?What is fitting loss?Where the length of the pipe is relatively long, the effect of the fitting losses are usually considered as minor losses, and are often ignored during initial analysis of the pipe system.Pipe Fittings Loss Calculations with K Factors9. FRICTION LOSS ALONG A PIPE - FIT

Loss of head is incurred by fluid mixing which occurs at fittings such as bends or valves, and by frictional resistance at the pipe wall. Where there are numerous fittings and the pipe is short, the major part of the head loss will be due to the local mixing near the fittings. For a long pipeline, on the other hand, skin friction at the pipe wall9.

pipe. For PVC pipe, the standard C value is 150. New steel 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 BEST PRACTICE MANUAL - NREDCAPa) Obstructions For normal, cylindrical straight pipes the major cause of pressure loss will be friction. Pressure loss in a fitting or valve is greater than in a straight pipe. When fluid flows in a straight pipe the flow pattern will be the same through out the pipe.
