Duct Calc constant pressure

Duct Calculator computes the size of air channels through the constant pressure drop method.

The calculation is performed assuming that the pressure drop per unit length along the pipe is a constant.
The Øeq hydraulic diameter corresponds to the diameter of a circular channel that would cause the same loss of load of the real geometry, equal to resistance coefficient of the motion of the air.
After calculating the app will send to your e-mail address a text file with all the channels' branches calculated.
