Most people dont size the duct properly for the airflow needed or they do not take into account the length of the duct. Think about it in terms of car exhaust.

Mind giving some concrete numbers? For the antminer s9 for instance, is 8 feet too long?

Also people will use inline fans that are not cfm matched to the amount of flow you are trying to create

It seems the s9 for instance its around 200m³/hr which translates to around 120ft³/min or CFM. Would people generally assume linear growth? e.g. 10 miners ==> 10 * 120 = 1200 CFM?

Just did a quick write up
