Transcribed Image Text:B. If a pipeline is located between two storage tanks as with example 3.2
(Textbook, p. 142), why should an engineer decide to install the pump close to
the tank from which the liquid is to be transferred from? Is the operation of
the pump in example 3.2 safe given the data of the problem?
Example 3.2-Unloading Oil from a Tanker
Specified Flow Rate and Diameter
General. The following statements apply oqually to Examples a.2, 3.3, 34,
and 3.5. Fie EL2 shows a pump that transfers a steady strenm of 35°API crude
ail from an eil tanker to a relinery stoenge tank, boch fre surfas being open to
the atmspbere. The effoctive kngth-lncluding fiting of the cummercial steel
pipe is 6,000 E. The discharge at paint 4 is 200 a abeve the pump ezit, which is
Ievel with the free arface of oil in the tanker. Hemever, heeane of an interveming
hill, point 3 ls at a higher altitude then point 4. Lcones between points 1 and 2
mg be ignored.
The erude oil has the following peoperties: p- 68 I/n; - 182 cP; vapor
pressure p,- 4.0 psia
Syecific to Eauvpie 8.2. lmpiemeut the algotithm fur a Case 1-type peoblem.
If the pipeline is Schedule 00 with a nominal dismeter of 6 in., and the required.
flow rate is 506 gpm, what presure p is zeded at the pump exit? Solve the
problem first by hand cakulations, and then by a spreodsheet.
