Abstract
The current cost of electrical power is translated into an annualized value to be used for economic considerations in the selection of pumping equipment. Motor sizing guidelines are suggested to permit electric motors to operate nearer peak efficiencies. The need to provide adequate net positive suction head for centrifugal circulating pumps is illustrated. Situations are cited where variable speed drivers can be employed advantageously. Margins of safety and control valve pressure drops should be scrutinized.
