Pump characteristics during work at variable rotational speed and constant head are discussed. Characteristics of the upper slope of pump efficiency curve were determined for the cases of constant and variable growth of rotational speed The left-sided coefficient of pump efficiency correction was defined.}, type={Article}, title={Analysis of pump energy consumption in the upper slope region of efficiency characteristic curve}, URL={http://journals.pan.pl/Content/125098/PDF/8_MECHANICAL_50_2003_4_Szychta_Analysis_of.pdf}, keywords={pump efficiency, energy-consumption}, }
