it works for water and air...
The Moody diagram is a powerful tool for calculating the pressure drop in any flow system.
Given the flow parameter (Re) and the roughness parameter (k/d), you get the friction factor (f).
Using f, you can work out the pressure drop from:
dP = ½ ρ f L V2 / d
It's as easy as that!
It works for all fluids (water, air, refrigerant, glycol...).
Our Moody program helps you to work out the parameters and gives you the friction factor.
