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 pipes internal diameter (inches) and C is the Hazen-Williams smoothness pipe c factor for polyethylene pipe in switzerland What is the C factor of pipe?What is the C factor of pipe?As stated before, the C Factor is a representation of the roughness of pipe. To find out the reason why we need to measure or represent the roughness of the pipe, we must first learn a little about how water likes to flow. Water likes a nice, smooth, easy, and straight path to flow in, this is called a laminar flow.The C Factor of Pipe, What Exactly is It?? The Fire c factor for polyethylene pipe in switzerland What is the roughness coefficient of PVC pipe?What is the roughness coefficient of PVC pipe?Roughness coefcient is based on the material of the 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 byAppendix A Friction Losses for Water Flow Through Pipe

### What is turbulent flow in pipe corrosion?What is turbulent flow in pipe corrosion?Pipe corrosion and scale are taken into account via a pipes C Factor. Too many obstructions and the laminar flow will change into what is called turbulent flow. Turbulent flow is when the water makes contact with the obstruction and changes its direction.The C Factor of Pipe, What Exactly is It??
