This paper focuses on building a theoretical method, based on the calculation of hydraulic losses to predict the energy performance of a Low-specific speed Pump as Turbine (PaT) quickly and accurately that supported for the PaT’s impeller design. The Euler equation is built with the analysis of hydraulic loss calculation and flow phenomena passing on the machine.

The experiment results reveal suitability of using a mono block centrifugal pump in hydro turbine mode. The results confirm that the pump in hydro turbine mode operate at higher heads and discharge as compared to the pump mode operation. BEP (best efficiency point) for the pump in hydro turbine mode is lower than in pump mode operation. Correlations proposed by earlier researchers for performance prediction of pump in hydro turbine mode are also tested.

Wisler, Director, Aerodynamic Research Laboratory of GE Aircraft Engines.2 .Turbomachines The complete material for Chapter 12 is contained in the E-book only. In previous chapters we often used generic “black boxes” to represent fluid machines such as pumps or turbines. The purpose of this chapter is to understand from a fluid mechanics standpoint how these devices work.

Pipe stress analysis calculates the stress in a piping system subject to normal operating loads such as pressure, weight, and thermal expansion, and occasional loads such as wind, earthquake, and water hammer. Because all piping systems are connected to equipment such as vessels, tanks, pumps, turbines, and compressors, the piping stress analysis also involves evaluation of the effect of the piping forces and moments to the connecting equipment. As the piping stress is controlled by the arrangement of the supports and restraints, the scope of piping stress includes also pipe supports.
