Using Table 64, select a combination of in-line blenders to mix ferric chloride with a design flow rate that varies from a minimum of 8,200m3/d in winter to a maximum of 49,200m3/d in summer. The design water temperatures are 4C in the winter and 15C in the summer. The plant will operate 8 hours per day for seven days per week in the winter and 24 hours per day for seven days per week in the summer. Assume that the water power is 80% of the motor power and that mixing time must be between 0.3 and 0.8s. Because this problem will require some iteration, a spreadsheet solution is highly recommended.
