Chapter 6 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
Download free Excel spreadsheet templates for Darcy Weisbach equation/pipe flow calculations. Frictional head loss and pressure drop can be calculated for given pipe flow rate, pipe diameter and length, pipe roughness, and fluid density and viscosity. Also the required pipe diameter to carry a given flowrate with a maximum allowable head loss can be calculated. The Excel formulas use an ...
