I don't know much about HVAC and I am working on a sewer ventilation project.
We want to ventilate a vortex drop structure (approx 80 m3) with 12 air changes per hour which gives us an air flow of 260 L/s. The air duct from the vortex structure to the exhaust fan is 78m long, 600mm in diameter and is made of HDPE. The fan is connected to a vent stack 300mm wide and 10m high, the outlet velocity we want to achieve is 12m/s with air flow of 300L/s therefore the stack outlet diameter is 180mm.
How do I choose an exhaust fan to achieve these parameters?
