2820 Question 2 (a) Explain with the help of specific energy diagram about two types of flows that are possible in a given channel carrying constant flow. Also, comment on the flow condition in the channel when specific energy is minimum. 10 Marks (b) Water is flowing at normal depth in a 3 m wide trapezoidal channel with a bed slope of 1:1500 and side slopes of 1H:1V. If Manning's coefficient n = 0.013 and the flow rate is 1.2 m3/s: (1) Calculate the height of a hump in the channel that would produce critical conditions without a rise in the upstream water level. height = 0. ostm 10 Marks (ii) Comment on the upstream water depth in the channel, if the provided hump height is more than the value calculated above. 5 Marks
