Position and type of resisters

10m

How many resisters?

L < 1,5 * W

10 < (1,5 * 7 = 10,5)

L < 3 * H

10 < 3 * 3,5 = 10,5

in theory, 1 resister could do

but the airflow = 896 l/s is

TOO BIG for 1 resister

7m

For a better air distribution, to avoid draft and noise, we select 8 diffusers

H = 3,5 m

Airflow=896l/s
