2. Ā sluice gate blocks the flow of water in a rectangular aqueduct with a width of 4.2 m with a flow rate of 16 m3/second. The upstream water depth marked with number 1 is 2.8 m and the downstream marked number 2 has a depth of 0.7 m. What is the magnitude of the force experienced by the floodgate? Fr, 1 1 2
