Unformatted text preview: Quiz 6 Solutions to selected questions Q. 1 The present pumping rate of North Slope crude oil through the Alaska Pipeline (see the chapter-opener photo) is about 600,000 barrels per day (1 barrel = 42 U.S. gallons). What would be the maximum rate if the Fow were constrained to be laminar? Assume that Alaskan crude oil ts ig. A.1 of the Appendix at 60C. Solution: rom ig. A.1 for crude at 60C, = 0.86(1000) = 860 kg/m3 and = 0.0040 kg/m-s. rom Eq. (6.2), the maximum laminar Reynolds number is about 2300. Convert the pipe diameter from 48 inches to 1.22 m. Solve for velocity: Q 1 or Fow of SAE 30W oil through a 5-cm-diameter pipe, from ig. A.1, for what Fow rate in m 3 /h would we expect transition to turbulence at 20C ? Solution: or SAE 30W oil take and take = 0.29 kg/m s at 20C (Table A.3) and 0.01 kg/m-s at 100C (ig A.1). Write the critical Reynolds number in terms of flow rate Q: Q 2 or Fow of oil ( = 0.1 kg/(m s), SG = 0.9) through a long, straight, smooth 5-cm-s), SG = 0....
