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. The pipeline described in Problem 6.7.1 is […]

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. 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. The origin pump […]

A water pipeline consists of three pump stations, each having one constant-speed motor-driven pump of 2000 HP. The analysis of current operations shows that the pipeline has been operating at a fairly constant flow rate of 3000 gal/min, and the pump throttle pressures are as follows: A water pipeline consists of three pump stations, each […]

This week is MUSEUM week! Find an art gallery or museum near you to explore and study. Bringing a piece of paper and pen with you, take down notes as you work your way through the space and capture the emotions you feel. Maybe you feel inspired or sad. Why? Write it down. Perhaps you […]
