Description

Design transmission pipes based on the universal formula.

 

Transmission pipe calculations based on the Darcy-Weisbach equation.

 

Performs calculations concerning gravity pressurized transmission pipes using the Darcy-Weisbach equation.

 

Given the geometric characteristics of the transmission line, offers five calculation alternatives:

 

  • Calculates the downflow elevation
  • Calculates the pipe diameter
  • Calculates the pipe length
  • Calculates the pipe roughness coefficient
  • Calculates the flow
