Metric Duct Sizing:

Apply the equal velocity method to determine the optimal size and configuration of ductwork for the specified system. Complete the attached chart accordingly. Ensure that the maximum duct depth does not exceed $250mm.$ Whenever feasible, prioritize the use of round ducts; however, if the dimensions exceed $250mm,$ rectangular ducts may be necessary.

Round Velocities: Mains: $12\frac{m}{s},$ Branches: $10\frac{m}{s}$

Rectangular Velocities: Mains: $11\frac{m}{s},$ Branches: $8\frac{m}{s}$
