Fitting head loss values
WebUsing K value to calculate frictional losses in a piping system. Equivalent length, L eq = K × (D/4f) where, K is the K value for a fitting (or for all fittings combined) D is the pipe diameter. f is the Fanning friction factor. You can use this equivalent length is used in the above Darcy's equation, to calculate the frictional pressure ... WebValves can cause almost no head loss at all to almost a complete loss of head. This depends on how the valve is position and what type of valve it is. If the valve is all the way open there will be a very small head loss coefficient such as the ball valve in Figure-5 with a k-value of 0.05. Such a small value shows that there is very little
