K-Factors are calibration values (pulses per unit of volume) used to convert flow sensor output frequencies to flow rates. This calculation tool helps you to determine the correct K-Factor for your flow sensor. GF Signet publishes K-Factors for water only in gallons Puhui Pipe manufacturer in China
HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or HDPE mains pipelines. Made from the thermoplastic HDPE (high-density polyethylene) , its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines.

HDPE-D occurs at much longer times compared to that of HDPE-A. Further, for any given stress within the brittle fracture regime, the failure time for HDPE-D is considerably longer. These observations clearly indie that the HDPE-D pipe is generally more
on equivalent pipe roughness is unlikely to be as severe as the influence of biological slimes in a heavily slimed sewer. For these reasons the concrete pipe industry recommends the adoption of a “ks” value of 0.6mm for most stormwater drain designs, but this
Calculating Entrance and Exit Losses Listed below are K-values for several common entrance and exit geometries. These may be used in conjunction with the velocity of the fluid in the pipe to calculate the entrance and exit pressure losses. Refer to the article on pressure loss calculation using the K-value or excess head method for the formula by which the pressure loss may be calculated from Puhui Pipe manufacturer in China
Concrete Pipe Association of Australasia (3) recommends the adoption of a ks value of 0.6 mm for most stormwater drain designs, but this value should be modified through engineering judgment where additional data is available. With these factors in mind it is
