Description

Calculate the head loss in water flowing through pipes using the Darcy-Weisbach formula and the Churchill correlation for determining the friction factor.

There are 5 calculation possibilities:

• Calculate head loss
• Calculate diameter
• Calculate pipe length
• Calculate equivalent roughness
• Calculate flow rate
