Hydraulic structure Q.2: Given the following data of a head regulator: The discharge= 60 cumecs, bed level of the canal-52.2m, crest level of the regulator=52.8m, upstream water level-54.2m, downstream water level=53.9m. The dimension of gates= (2.5x3)m and the thickness of the piers is 0.9m. Neglect the velocity head and use coefficients of discharge= 0.8 and 0.577. Determine the water way of the regulator

Expert Solution

Step 1: Given data:

Discharge $left parenthesis straight Q right parenthesis space equals space 60 space cumecs$

Bed level of the canal $equals space 52.2 space m$

The crest level of the regulator = $52.8 space m$

Upstream water level = 54.2 m

Downstream water level = 53.9 m

Dimensions of gates = $2.5 space m space x space 3 space m$

The thickness of the piers = 0.9 m

Coefficient of discharge for gates = 0.8

Coefficient of discharge for piers = 0.577

Acceleration due to gravity $left parenthesis g right parenthesis space equals space 9.81 space m divided by s ²$
