factor was. The “C” factor is considered to be a measurement of the smoothness of the pipe wall. The formula for determining pressure drop, over a 100 foot section of pipe is ∆P100 = (452*Q 1.85)/(C 1.85 *D 4.86), where Q is the rate of flow (GPM), D is the
HDPE Pipe is a robust, flexible piping system, used for fluid and gas transfer across the world. Polyethylene’s toughness, immunity from corrosion, excellent resistance to chemicals and low weight have contributed to its continued appeal for use in situations where cost-effective and reliable piping systems are required.

* HDPE pipe may face; PE density of 94% of the salt water, because it is up to 96% of the fresh water on the HDPE pipe filled with water even if the water is suitable to swim in. Therefore, be reduced as far as large parts of the ground may be left floating on the water coined.
C Factor A factor or value used to indie the smoothness of the interior of a pipe. 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.
The HDPE Pipe Model, developed by the PE100+ Association with inputs from many industry experts, includes the most frequently asked questions and answers (Q&A''s) of all the elements through the pipe system value chain: design, materials, construction
Hazen Williams C Factor is 150 and doesn''t change over time - Benefit * HDPE pipe has a smooth ID that does not corrode or tuberculate and maintains its flow capability over time. * The C Factor of Ductile Iron pipe is dramatically reduced over time due to
