1. Design a rapid mixing tank by using the following information. a. Find the dimension of the tank, depth & width. Assume 2 tanks. Comment on depth/width ratio. Flow rate is (0.3+0.1x4) m3/s, detention time is 50 sec, velocity gradient is 700 1/s. b. Find motor power required for mixing by C assuming motor efficiency, s n, is 0.9 and viscosity 1.206110-3 m2/s. C. Design paddles by assuming paddle length/tank width ratio is equal to 0.4. Also, take paddle width/length ratio is 5. The coefficient of K is 6.3 for paddles.(a=4)
