A 3-ft-diameter horizontal duct is used to carry ventilating air into a vehicular tunnel at a rate of 9000 ft/min. Tests show that the pressure drop is 1.5 in. of water per 1500 ft of duct. What is the value of the friction factor for this duct? The specific weight of water is 62.4 lb/ft³. Use 0.00236 slugs/ft as the air density.
