Pipe Fittings Loss Calculations with K Factors

Pipe Fittings Loss Calculations with K Factors Pipe fittings, valves and bends usually have some associated K factor or local loss coefficient, which allows the calculation of the pressure loss through the fitting for a particular fluid flowing at a specified velocity.

Some Friction Loss Tables

Example: Determine L (friction loss in pipe fittings in terms of equivalent length in feet of straight pipe). Assume a 6" angle valve for Schedule 40 pipe size. Select the appropriate K value for such and select D and f for Schedule 40 pipe from the table below where K is the pipe diameter in feet.
