I only have data the CFM (cubic feet per minute) of the axial exhaust fan that we use. My question is, can I calculate design the hood, the measurement (inch) flexible hose/duct of LEV (local exhaust ventilation) by using Bernoulli?
Or I must have another parameter such us pressure or something else?
