Determine the required width of the paddle blade and recommend a motor power (in watts) and rotational speed (in rpm) for the horizontal shaft a cross-flow paddle flocculator for the first compartment of a three-compartment flocculation basin shown in Figure P-6-23. (Note: there are three paddle wheels on one shaft.) Figure P-6-23 and the following assumptions are to be used in the design:
