What are the dimensions and the actual power required for a square rapid-mix basin that is to be used to treat 0.15 m3/s of water if the detention time is 10 seconds? The depth is assumed to be 1.5 times the width. The velocity gradient is 600 1/s. The average temperature of water is 5 degrees C. The efficiency of the mixer and motor is 80%.?
