The present pumping rate of crude oil through the Alaska Pipeline, with an ID of 48 in, is 5s0.000 barrels per day(1 barrel = 42 USS gallons). (4) Is this

a turbulent fiow? (6) What would de the maximum rate if the flow were constrained to be laminar? Assume that Alaskan oil fits Fig. Al of the Appendix at 60°C.
