Graf, Edward; Marchi, John F. (Texas A&M University. Turbomachinery Laboratories, 1997)Chemical and process plants usually contain numerous valves and pumps in a complex network of pipe runs. Plant design and pump selection are usually based on steady state design conditions. However, the opening or closing ...

Cooper, Paul; Sloteman, Donald P.; Graf, Edward; Vlaming, Dirk J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)The suction-stage impeller of a large crude oil pipeline pump was designed by combining quasi-three dimensional flow analysis with current theories to generate an impeller geometry, which was evaluated in a half-size model ...
