A rectangular channel is 4 m wide, and it reduces to 2 m through a hydraulic structure. Assuring the transition to be horizontal and the flow to be frictionless determine the water surface elevations upstream of the constriction when the specific energy at the constriction is 6 m. Assume choking occurs, hence critical flow equations are applicable. Note: Hand written solution is not allowed.

Example 5.23 Two 30 cm wells completely penetrate an artesian aquifer of thickness 15 m ell decreases. spaced at 200 m. Permeability of the aquifer is 60 m/day. When one well is pumped at and are the rate 2000 Ipm, the drawdown in the well is 5 m. Assume a radius of influence of 300m and steady state conditions. What will be the discharge when both the wells are pumped keeping the drawdown at 5 m. If a third well is located at 200 m to form an equilateral triangle and all the three wells pumped keeping the drawdown at 5 m, what is the percentage reduction in discharge ? What is the percentage reduction in discharge if another well is added to form a square ?

A trapezoidal channel has a bottom width of 6 m and side slope of 1:1. The depth of flow is 2 m at a discharge of 24 m³/s. What would be the specific energy (take, q = 10m/(s^ 2))?

Find the corresponding hydraulic conductivity of aquifer when discharge 3 through the aquifer is 1500 m³/day. The length and width of the aquifer normal to the discharge direction is 10,000 m and 1500 m respectively. 300 m and 250 m are the hydraulic heads at the entry and exits points of aquifer respectively.

A trapezoidal channel has a bottom width of 6m and side slope of 1:1. The depth of flow is 2m at a discharge of 24 m³/s. What would be the specific energy (take, g = 10m /(s^ 2))?

A 10 m wide rectangular channel has a sluice gate, as shown. The depths are measured as y1 = 1.00 m and y2 = 0.60. Use the Specific Energy (E1 = E2) to calculate the flow rate Q.

Water flows through a 4m wide rectangular channel at a flow depth of 0.5m. Then, a hydraulic jump occurred. If the upstream velocity is 10m/s, solve the dissipation ratio.

Two reservoirs are connected through a 900 m long, 0.5 m diameter pipe, which has a gate valve. The pipe entrance is sharp (loss coefficient = 0.5 ) and the valve is half-open (loss coefficient = 5.5). The head difference between the two reservoir is 10 m. Assume the friction factor for the pipe as 0.03 and g = 10 m/s2. The discharge in pipe accounting for all minor and major losses is?
