Consider SAE 30W oil flowing through a 1 in.-diameter, 12 ft long horizontal section of pipe. The pressure drop is 0.60 psi. Using fully developed laminar flow results (from H1.2 or text), determine: a. shear stress (lbf/ft) on the pipe wall, and also at distances of 0.2 and 0.5 in away from the wall, b. volume flow rate (ft/min), c. verify that the flow is laminar. d. Redo parts a.-c. with the pipe incline at = 25 and same applied pressure gradient. Is the flow up or down? 1 x 10- 8 6 4 2 ? 06 + 1 x 10- 8 4 2 + 06 + - 1x 10-4 8 2 1 x 10-5 8 06 4 2 60064 1 x 10-6 8 2 1 x 10-7 8 -20 Octane SAE 30W oil Glycerin SAE 10W-30 oil Carbon dioxide Kerosene Water Mercury 20 SAE 10W oil 40 60 Temperature, C Helium Hydrogen 80 Methane Air Heptane Carbon tetrachloride. 100 120 Consider SAE 30W oil flowing through a 1 in.-diameter, 12 ft long horizontal section of pipe.
