What are the hydraulic diameter and radio?
posted in Technical Articles by TecnoConverting
The hydraulic diameter is a characteristic parameter of a tube section or generic cannel, and allows studying the flow behavior just as if it was circular.
Where,
– A is the cross sectional area of the channel
– P is the humid perimeter
It´s important to note that the hydraulic radius (Rh) is not half the hydraulic diameter. Both parameters relate them self by the following:
Example of hydraulic diameter calculation for TecnoTec lamella H80:
The hydraulic diameter of a lamella TecnoTec H80 is calculated as follows:
Where,
and,
(a is the apotema)
Replacing values in the hydraulic diameter formula, it is easy to calculate that:
