We know that this duct also demands a quantity stream rate of 0.79m3/s so we can easily utilize the velocity and volume movement price to find the lacking facts.
The horizontal traces are for volume flow amount. The downward diagonal strains are for velocity, the upward diagonal lines are for duct diameter.
The next section would be the devices accustomed to evaluate the airflow with the diffuser and grille. Typically, we utilize a circulation hood to seize the airflow of diffusers.
