A duct system layout is shown in the figure below, it is supplied with air from a
central air conditioning unit. The ducts require to be rectangular with a
maximum height of 10in due to ceiling limitations. Maximum air duct velocities
are: main = 1200fpm; branches = 800 fpm. Determine the sizes of the
rectangular ducts and the static pressure at the AHU. Use Velocity reduction
method.
