"C" Factor Coefficient testing can be provided with accurate results utilizing HETEK Solutions Inc. professional services, their standard and proven field procedures, municipal experience, and high technology equipment.
When conducting a water model of a distribution system it is imperative that certain parameters of the system be known. Some of the parameters are pipe material, size, age, and roughness coefficient of the pipe. If you know the pipe material, age and size of the pipe, one can assume standard approximations to enter into the water-modeling program. This assumption alone can alter the outcome of the water model so it is not even representative of the distribution system. One way is to provide defendable field data. HETEK Solution Inc. has included electronic technology to accurately calculate the actual C-Factor of a given pipe within the water distribution system.
Using experienced field representatives to provide all preliminary system data prior to flow testing a section of pipe for analysis, and high resolution pressure logging devices in conjunction with the appropriate flow measurement equipment, accurate and reliable results can be obtained. The data obtained from the field data results will enhance the accuracy of the computer model and provide known parameters to work around. In order to be able to conduct a "C"coefficient in existing mains, one must ensure that sufficient head loss is achieved within the desired pipe section.
This is accomplished by producing large enough flow rates, which in turn create high velocities and high friction or head loss within the pipe. The high-resolution pressure transducers and flow metering equipment are data recorded electronically to provide a "picture snapshot" of the field-testing. This data is used to conduct the C-Factor calculation.
