We want to transport 500 ft3/min of air horizontally from our air conditioner to an outbuilding 800 ft away. The air is at 40oF and a pressure of 0.1 psig. At the outbuilding the pressure is to be 0.0 psig. We will use a circular sheet metal duct, which has a roughness of 0.00006 in. Find the required duct diameter. by using moody chart for find f friction factor

A 3-ft-diameter duct is used to carry ventilating air (???=2.373×10-3???slugs/ft3, ???=1.57×10-4???ft2/s) into a vehicular tunnel at a rate of 9000 ft3/min. Tests show that the pressure drop is 1.4 in. of water per 1500 ft of duct. What is (a) the value of the friction factor for this duct and (b) the approximate size of the equivalent roughness of the surface of the duct?
