(ft H 2 O) K Data Analysis Determination of the coefficient K consists of plotting the experimental local loss coefficients versus the corresponding Reynolds numbers (Re = VD/n, where D is thepipe diameter and n is the kinematic viscosity) for known discharges through the device.pipe fitting loss coefficients in burmaloss coefficients in pipespipe flow loss coefficient bendentrance loss coefficients pipesSome results are removed in response to a notice of local law requirement.

The flanged elbows allow for a smooth transition from one direction to another while the threaded elbows provide a rough surface for changing direction. When a pipe splits into two or when two pipes converge into one, there will be minor losses.
