The airflow level is not the similar point as velocity. Velocity refers to exactly how much floor air covers relative to time. In the meantime, the airflow amount highlights air output mainly because it pertains to time.
The horizontal traces are for quantity flow amount. The downward diagonal strains are for velocity, the upward diagonal traces are for duct diameter.
Then we will work out the dynamic reduction for that air which turns in to the bend. For this we use the same formulation as prior to. Velocity out didived by velocity in to search out our velocity ratio.
