A pump station is required to deliver 20°C water from a reservoir to an elevated srorage tank at a minimum required discharge of 300 L/ sec. The difference in elevations is 15 m, and a 1,500-m-long, wrought-iron pipe that is 40 cm in diameter is used. Select the pump(s) from the set given in Figure 5.24. Determine the number of pumps, the configuration (series or parallel), discharge, total head, and efficiency at which the pumps operate. Ignore minor losses.
