A canal was constructed for an irrigation project as shown. The canal was designed to carry a discharge of 45 m3/s for a flow depth of 2 m with a bed slope of 1 in 5000. The side slopes of canal is given by 1V : 1/2 H. The critical velocity ratio is taken as 1.05 and N = 0.0225. What will be the perimeter of the section______ m
