WebK factor - the ratio of pressure loss over the dynamic pressure Cd or discharge coefficient - the ratio of the actual flow rate of the fluid through the fitting over the frictionless flow rate. The calculated values are typical. Manufacturers data should be used if it is available. WebMay 4, 2015 · The resistance coefficient K can be thought of as the number of velocity head loss caused by a valve or fitting. The value of K is constant when the flow is in the zone of complete turbulence. The value of K can be calculated from the geometry of the valve or fitting based on empirical results obtained from a variety of test data.
