Question 5 The figure below shows channel flow over a bump, which results in a hydraulic jump downstream. The flowrate per unit width in the channel is 1.6 m's7. If the depth at point 1 is 100 cm, determine: (a) the depths at points 2, 3 and 4 (b) the bump height, Ah (c) the fraction of flow energy dissipated in the hydraulic jump(4 marks) (7 marks) 4 marks) 4 Jump Ah

Question 7 Consider flow in an open channel with slope 1:500 and a Manning's n of 0.030. The channel has a rectangular cross-section with a width of 5 m (a) Uniform flow in this channel has a depth of 1.6 m. What is the flowrate in the channel? (4 marks) (b) Suppose that this uniform flow (at point 1 in the figure below) encounters an obstacle on the channel bed (at point 2). How big would the obstacle need to...

A trapezoidal channel has a side slope of 1:1 and a bed width of 6.0 m. A hydraulic jump with a height of 0.5 m (i.e. the difference between water surface elevation upstream and downstream of the jump) is encountered in the channel. If the channel has a discharge of 10 m3/s, determine the critical depth in the channel. Plot the momentum curve and determine the flow depth immediately upstream and downstream of the jump.
Uniform water flow in a wide brick channel of slope 0.02 degrees moves over a 10-cm bump. A slight depression in the water surface results. If the minimum water depth per meter of width Then, again a...
Uniform water flow in a wide brick channel of slope 0.02 degrees moves over a 10-cm bump. A slight depression in the water surface results. If the minimum water depth per meter of width Then, again assuming uniform subcritical approach flow (V., y find (c) the flow rate and (d) y2 for which the flow at the crest of the bump is exactly critical (Fr2-10)

EXPERIMENT 4 FLOW UNDER A SLUICE GATE AND THE HYDRAULIC JUMP 4.1 Introduction The sluice gate provides acenvenient means of flow regulation, especially in irrigation and drairage schemses where low has to be distributed in notworks of interconnected chanmels. The gane is peovided wih a lifting mechanis so at the aperture beeeath it may be set to any desired position When closed, the sperture is closed so that no Bow ca pass through the gale. In this experiment we measure...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
