Question

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 equally to Examples 3.2, 3.3, 3.4,
and 3.5. Fig. E3.2 shows a pump that transfers a steady stream of 35°API crude
oil from an oil tanker to a refinery storage tank, both free surfaces being open to
the atmosphere. The effective length-including fittings of the commercial steel
pipe is 6,000 ft. The discharge at point 4 is 200 ft above the pump exit, which is
level with the free surface of oil in the tanker. However, because of an intervening
hill, point 3 is at a higher altitude than point 4. Losses between points 1 and 2
may be ignored.
The crude oil has the following properties:p = 53 lbm/ft3; µ = 13.2 cP; vapor
pressure p, = 4.0 psia.
Specific to Example 3.2. Implement the algorithm for a Case 1-type problem.
If the pipeline is Schedule 40 with a nominal diameter of 6 in., and the required
flow rate is 506 gpm, what pressure p2 is needed at the pump exit? Solve the
problem first by hand calculations, and then by a spreadsheet.
