A water treatment plant has three flocculation compartments that water flows though sequentially (in series). The water is gently mixed in each compartment with rotating paddles, and the power input decreases as water moves through each compartment: Compartment #1: 186 W; Compartment #2: 30.0 W; Compartment #3: 7.50 W. Each compartment is 4.17 m deep, 3.75 m wide, and 4.17 m long. The water temperature is 15 °C the flow rate is 16,000 m3/day. Calculate the velocity gradient for each compartment.
