The present pumping rate of crude oil through the Alaska Pipeline with an ID of 39 in is 550,000 barrels per day (1 barrel is 42 U. S. gallons). For crude oil at 60ºC, take ρ = 860 kg/m3 and μ ≈ 0.004 kg/m·s. What would be the maximum rate if the flow were constrained to be laminar? Take π = 22/7. Answer is asking for maximum flow rate for barrels per day

QUESTION 22.1. A water hammer is a phenomenon caused by the sudden increase or decreasein fluid velocity which results in pressure fluctuations in a pipe.A common cause of the water hammer is rapid closure of a valve in apipeline. In order to minimise the pressure rise, the closure time of thevalve needs to be increased. If a pipe (K = 18.9 x 105 kPa) is laid for adistance of 1500 m, which of the following would be considered a gradualvalve closure time?(a) 1.3 seconds(b) 5 seconds(c) 2.18 seconds(d) All of the above 2.2. hich of the following is considered a minor friction loss in pipe system?(a) Slight changes in elevation(b) Shock losses due to a pipe contraction(c) Head loss due to pipe friction(d) Head loss when the fluid passes through a valve.
