The pipeline described in Problem 6.7.1 is used to batch ANS crude along with a light crude (0.85 specific gravity and 15 cSt viscosity at 60°F). Determine the optimum batch sizes to reduce pumping costs based on a 30 day operation. Consider a flow rate of 6000 bbl/hr.

In Problem 7.14.2 for gasoline movements, the pump used has a head versus capacity and efficiency versus capacity as indicated below:

January 27, 2022

A tank farm consists of a supply tank A located at an elevation of 80 ft above mean sea level (MSL) and a delivery tank B at 90 ft above MSL.

A pump station installation at Corona consists of two pumps configured in series each developing 1500 ft of head at 4000 gal/min.

January 27, 2022

Use the data in Example Problem 8.1 and consider one of the two pumps driven by a variable-speed electric motor.

The origin pump station at Harvard on a 50 mile pipeline consists of two pumps in series, each developing 1450 ft of head at 3000 bbl/hr.

January 27, 2022

If a VSD pump is used in Problem 8.5.1 above, determine the speed at which the pump should be run to maintain the flow rate of 3000 bbl/hr. The rated pump speed is 3560 RPM.
