TY - JOUR AU - Al-Rababa, Khalid S. PY - 2005 TI - The Operational Features of Pumping Stations Equiped with Parallel-Connected Centrifugal Pumps for Land-Reclamation JF - American Journal of Applied Sciences VL - 2 IS - 1 DO - 10.3844/ajassp.2005.423.425 UR - https://thescipub.com/abstract/ajassp.2005.423.425 AB - The required water supply of a pump could be provided by means of different combinations of pressure piping and pumping units at different operational costs. The basic indices describing the operational modes for the individual and group pumping units, including the values of the efficiency, are computed. The adequacy of the calculational results that based on the developed mathematical models is confirmed by the full-scale experimental researches. Based on the presented principles of the load distribution between parallel working pumping units, 5 % of consumed electric power may be saved.
