Question:

Air (20°C) flows with a speed of 10 m/s through a horizontal rectangular air-conditioning duct. The duct is 20 m long and has a cross section of 4 by 10 in. (102 by 254 mm). Calculate

(a) The pressure drop in inches of water and

(b) The power in watts needed to overcome head loss. Assume the roughness of the duct is k_s = 0.004 mm. Neglect component head losses.
