Problem #4: SAE 30 oil flows steadily from a tank through a 200 ft length horizontal pipe having a diameter of 4 inches. A pitot-static probe is used to measure the dynamic pressure at the centerline of the pipe, beginning from the inlet of pipeline to a location far from the entrance. A plot of the dynamic pressure as a function of axial location shows that the dynamic pressure initially increases and becomes constant after a distance x = 25 ft from the inlet. Determine: a) the dynamic pressure at point x = 25 ft, b) the static pressure at x = 25 ft SAE 30 Weight Oil Pitot-static tube 4 inches Oil flow Dynamic pressure at centerline of pipeline x=0 Increasing dynamic pressure Constant dynamic pressure Axial position, x x = 25 ft (outlet x=200 ft)
