Problem 6 A truck is ruptured and releases a non-reactive liquid into a streamline, which drains into a retention pond with a 20,000 m3 liquid volume. The streamline has a velocity of 0.10 m/s and a flow rate of 0.10 m3/s. It is 5000 m from the spill site to the pond. Assume that the pond operates like a CSTR with balanced flow (Qin=Qout) Calculate the time required to reach the pond (in days) Estimate the time it will take to flush the following percentages of the liquid from the pond.

Q/A small resarvoir has a spillway with the Following relationship S = 4000 O Where S is storage in m3 and O is the outflow in m3/s Assume the initial outflow is equal to zero .Rout the Following inflow hudrog raph through the reservov Time hur : 0, 1,2,3,4,5,6,7. inflow m3/s: 0 ,30 , 100 , 80 ,60, 40, 20.
A 7350 m long, 1050 mm concrete pipeline connects an upstream reservoir (watersurface elevation 433.3 m) to a downstream reservoir (water surface elevation 423.1 m). Adischarge valve at the downstream end is used to control flow; when this valve is fully open,the measured discharge in the pipeline is 920 L/s under the naturally available head difference.(a) Assuming fully developed turbulent flow and that all other local losses are negligible,estimate the loss coefficient k for the fully open valve (assume f = 0.015).(b) Because of increasing urban development, the flow under the natural head difference isconsidered to be inadequate and it is proposed to increase this flow with pumping. The head-capacity curve for the pump can be approximated by the equation H = 8 – 3.5Q2 in which H isthe total dynamic head on the pump (in m) and Q is the discharge (in m3/s). What is thedischarge that can now be obtained from the system where the pump is installed at a cross-section of the pipeline?
Three reservoirs A, B and C whose water surface elevations are 60ft, 50ft and 32 ft respectively, are interconnected by a pipe system with a common junction at elevation 35ft. All pipes have a frictional factor of 0.020 and are as described as follows 1. Illustrate the problem 2. What is the direction of flow into reservoir B? 3. Determine the flow from reservoir B in ft^3/s. Indicate if it is Toward or away from junction D. 4. Determine the flow from reservoir C in ft^3/s. Indicate if it is Toward or away from junction D.
1. Find the flow rate out of reservoir A. 2. Find the flow rate towards reservoir C. 3. What is the elevation of reservoir C.

If the flow into a 20 m wide x 85 m long x4 m max height detention basin occurs at a constant rate of 1.7 m3/s, the time to fill the basin is: A) 1hour 6 minutes 40 seconds B) Cannot be determined without information on what is the value of 1 unit. C) cannot be determined without additional information on the inflow hydrograph D) 1 hour
(i) On the apron of spillway model built to a scale of 1 : 25, a hydraulic jump of 115 mm is formed and time required to open the spillway gate is 90 sec. If the discharge in the prototype spillway is 1200 cumec, then determine height of the jump in prototype, time in the prototype to produce the same surge effects in model and discharge over the model.
