D. Measuring the Supply Discharge velocity from the MB Blade
There are two sizes of MB Blade Discharge Grills.
MBFront41x06 with a perforated discharge dimension of
41.5” wide x 6” high. The face area is 1.38sq feet
MBFront33x06 with a perforated discharge dimension of 33”
wide x 6” high. The face area is 1.1 sq feet
When using a hot wire anemometer take 12 velocity readings
at each discharge grill. Take 6 readings across the length and
2 rows. See Chart No5 below to convert the average velocity
reading per grille to CFM.
