PVC Resistance Coefficient, K - Pipelines, Piping and

Dec 06, 2004· The way Crane correlates the K value it does seem to be affected by the friction factor - but this is just a "standard" friction factor that Crane have chosen to use and it has nothing to do with the actual friction factor (or pipe roughness) of the actual material. The Crane manual is a great resource, but this particular aspect has caused a

Reducer Equations in Crane TP-410 - Engineered Software

While the equations are different, the practical impact is small, as shown in the graphs below. There is little change in the resulting K value and therefore minimal difference in the calculated head loss (based on the flow of 60 °F water at 10 ft/sec). The K values from Equation 2-16 are the highest, and therefore the most conservative.

Calcium Silie

Thermo-12® Gold is a pre-formed, high-temperature, abuse-resistant pipe and block insulation.It has exceptional structural strength, and can be used on operating systems that reach 1200°F (650°C). Thermo-12 Gold is composed of hydrous calcium silie and is made with XOX Corrosion Inhibitor®, a proprietary formula and process that inhibits corrosion to the outside surfaces of pipe and

Pressure Loss from Fittings – 2K Method – Neutrium

Introduction. The 2K method allows the user to characterise the pressure loss through fittings in a pipe. As the name suggests, two K coefficients are used to characterise the fitting, which when coined with the flow conditions and pipe diameter may be used to calculate the K-value (excess head), which is in turn used to calculate the head or pressure loss through the fitting via the excess

K Value and Pipe Length Calculator

This calculator shows the relationship between the K value and pipe length. The K value for various fittings has been arrived at through experimentation. For any valve, a length over diameter (L/D) coefficient can be determined by equating the pressure drop through the valve to the equivalent length of pipe measured in pipe diameters.

Jan 02, 2007· Crane noticed that the friction factor in pipe, and the K value for fittings such as bends, varied with the diameter of the pipe at the same rate (assuming turbulent flow). It was convenient to link the K values to the friction factors because they (i.e the friction factors) were well documented.
