Hazen Williams Formula - Pipe flow

Unfortunately the results depend upon the value of the friction factor C hw which must be used with the formula and this can vary from around 80 up to 130 and higher, depending on the pipe type, pipe size and the water velocity. The imperial form of the Hazen-Williams formula is: hf = 0.002083 L (100/C)1.85 x (gpm1.85/d4.8655) where:

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 the Hazen Williams formula for the most commonly used steel and PVC pipe

High-density polyethylene - Wikipedia

High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene.It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomeranes and plastic luer.

C Factor - Water Programs

The higher the C Factor, the smoother the pipe, the greater the carrying capacity, and the smaller the friction or energy losses from water flowing in the pipe. To calculate the C Factor, measure the flow, pipe diameter, distance between two pressure gauges, and the friction or …

FAQ C Factor - Polyethylene Pipe - HDPE Pipe & Fitting

The C factor for HDPE butted fused pipe was found experimentally to be about 155. A conservative design value is 150. DI manufacturers publish an initial value of 140 for cement lined DI pipe. Many engineers assume that this value will be reduced over the life of a pipeline due to corrosion and use design values of 120 or 100.
