Formula to Calculate drop Pressure in Liquid Pipe

Click For Summary
SUMMARY

The discussion focuses on the formula for calculating pressure drop in liquid pipes and determining the appropriate pipe diameter for specific applications. Key formulas mentioned include the Darcy-Weisbach equation and the Hazen-Williams equation, which are essential for accurate pressure drop calculations. Participants emphasize the importance of using constant values such as fluid density and viscosity, along with pipe length and roughness, to achieve precise results. An example calculation is requested to illustrate the application of these formulas.

PREREQUISITES
  • Understanding of fluid dynamics principles
