Each designs use an air velocity of 5m/s, the colors stand for the velocity with blue that website means minimal velocity and crimson symbolizing the significant velocity regions.
By the point you finish altering the last diffuser, the very first diffuser should be enhanced from eighty% of the original airflow to close to a hundred% of the first airflow that is approximately what you should reach.
We go ahead and take chart and scroll up from The underside left till we strike the volume movement rate of 0.79m3/s. Then we Identify exactly where the velocity line is of 5m/s and we attract a line throughout until finally we strike that.
