2. A flocculation basin 60 feet long, 45 feet wide, and 14 feet deep treats coagulated water flow of 10 million gallons per day (MGD) at a temperature of 50°F, absolute viscosity, u 2.735 x 10^5 lb-s/ft^2. The power (P) input to the paddle wheel is 930 ft-lb/sec, resulting in a paddle blade tip velocity of 1.4 and 1.0 feet per second (fps) for the outer and inner blades respectively. Determine the following: (a) Detention time in hours (b) Horizontal flow through velocity (Vn) in feet per minute.
