1. OBJECTIVE |
|
Esta
Norma Mexicana establece el método para determinar el flujo de gases en
un conducto por medio del tubo de Pitot. |
|
This Mexican
Standard establishes the method for determining the flow of gases in a
flue by means of the Pitot tube.
|
|
El método
es aplicable para velocidades de gases superiores a 3m/s (9.84ft/s) en
promedio, y conductos con diámetros internos iguales o mayores a 10cm
(3.94in).
|
|
The method is
applicable for velocities of gases greater than 3m/s (9.84ft/s) in
average, and flues with internal diameters equal or greater than 10cm
(3.94 in). |
