Calculating External Static Pressure for DUCT
Calculating External Static Pressure for DUCT
(OP)
Hey,
a very quick question.
When you have a straight duct going out from an Exhaust Fan. Do you consider pressure loss at the branches that are feeding to the main line. ( index run)
if there is a grill at the duct run, do you consider any pressure loss for it?
please,

in the line, there are branches coming from the rooms.
1 corridor, 3 rooms, i am collecting air from each room, in the same duct.
do i consider pressure drop at the branches? or consider it as a straight duct till the final exhaust grill?

for you application, you consider suction and discharge parts of the index run, it is the external pressure that the fan has to face.
