Question
A 0.3 m diameter circular duct carries
standard air at a velocity of 360 m / min. It
is replaced by a rectangular duct having the
same pressure loss per unit length due to
friction. Determine the dimensions of the
rectangular duct if the aspect ratio is to be 1.5
for (a) the same volume flow through the two
ducts, and (b) the same velocity in the two
ducts.
