Pipe Friction Loss Calculations - Pipe Flow Software
Pipe Friction Loss Calculations Flow of fluid through a pipe is resisted by viscous shear stresses within the fluid and the turbulence that occurs along the internal pipe wall, which is dependent on the roughness of the pipe material.
Head loss | KSB
Head loss in a pipe See Fig. 1 Head loss (k) is the mean absolute roughness of the pipe inner surface for which approximate values are available depending on the material and manufacturing processes. Head losses in valves and fittings. The head loss (H L)
Typical input data which may be required for above calculations are: Fluid temperature, Aient Temperature, Pipe Size, Relative Humidity, Length of Pipe, and Flow Rate. Thermal k-values for the insulation products offered have been pre-selected. Note: information must be entered in all input fields for the program to operate.

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.
