At a point where an irrigation canal having a rectangular cross section is 18.5 m wide and 3.75 m deep, the water flows at 2.50 cm/s. At a point downstream, but on the same level, the canal is 16.5 m wide, but the water flows at 11.0 cm/s. How deep is the canal at this point?

Solution 39E This equation can be solved using the continuity equation, Av = constant, where A is the area of cross-section and v is the speed of liquid flow. Given, A = 18.5 m × 3.75 m 1 v = 2.50 cm/s = 2.50 × 10 2 m/s 1 Width of the canal = 16.5 m Let...
