Floor Height
How do I calculate how high I need my floor ducting to be?Answer:
We design an air distribution system to work on an air speed of 1800 to 2000 ft/min inside the main air duct and under the floor. From this we calculate the cross sectional area required in both instances and therefore identify the required duct size and the floor bearer depth.
