The Darcy friction factor ݂ for a smooth pipe is given by = 64/Re for laminar flow and by = 0.3/Re.ଶହfor turbulent flow, where Re is the Reynolds number based on the diameter. For fully developed flow of a fluid of density 1000 kg/m3 and dynamic viscosity 0.001 Pa.s through a smooth pipe of diameter 10 mm with a velocity of 1 m/s, determine the Darcy friction factor. _________
