Design of PE Piping Systems - Plastics Pipe Institute

Design of PE Piping Systems 159 The Hydrostatic Design Stress, HDS, is the safe long-term circumferential stress that PE pipe can withstand. It is derived by applying an appropriate design factor, DF, to the Hydrostatic Design Basis, HDB. The method for establishing the Hydrostatic Design Stress for PE pipe is described in Chapters 3 and 5.

PIPE FRICTION LOSS

PIPE FRICTION LOSS. In this example, calculate the total friction loss in a pipeline. Enter the flow rate, internal pipe diameter, and the type of pipe from the list supplied. Leave pipe length as 100 to get the friction loss per 100 m/ft of pipeline.

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.

Darcy–Weisbach equation - Wikipedia

In fluid dynamics, the Darcy–Weisbach equation is an empirical equation, which relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach.. The Darcy–Weisbach equation contains a dimensionless friction factor, known as the Darcy
