Question: Water at 1 0 deg C flows through a smooth 6 0 - mm - diameter pipe with an average velocity of 8 m

Water at 10\deg C flows through a smooth 60-mm-diameter pipe with an average velocity of 8m/s. Would a layer of rust of height 0.009mm on the pipe wall protrude through the viscous sublayer? First, determine the Reynolds number of the flow. Part 2, what is the friction factor. Part 3, determine the wall shear stress. Part 4 what is the friction celocity?
