Webb22 maj 2024 · Example: Moody Diagram. Determine the friction factor (f D) for fluid flow in a pipe of 700mm in diameter that has the Reynolds number of 50 000 000 and an absolute roughness of 0.035 mm.. Solution: The relative roughness is equal to ε = 0.035 / 700 = 5 x 10-5.Using the Moody Chart, a Reynolds number of 50 000 000 intersects the curve … WebbFriction losses in straight runs. Air flows at 6000 cfm through 80 ft of circular duct having a diameter of 28 inches. Compute the flow velocity of the air in the duct and the losses due to friction. Take the roughness of the duct to be that of medium smooth galvanized steel, \epsilon=0.0036~\inch. The air velocity is found from the continuity ...
