| Abstract: | Flow control of pumps with adjustable speed ac drives can be very economical. Pump and system head/flow characteristics are reviewed, with suggestions for estimating the pump characteristic and efficiency at reduced speed. Generalized pump and savings curves are then developed to permit quick checking of the economics of adjustable speed flow control for various system characteristics. |
