Define flow at a hydraulic jump (upstream and downstream) in terms of the types of flow and corresponding Froude number. What is the depth of water at each section (upstream and downstream) compared to critical depth? Not that a hydraulic jump can occur in the folowing situations: flow under a sluice gate, a change in slope from very steep to mild, flow over a weir. Draw each of these circumstances and describe why each of these circumstances can give rise to a hydraulic jump.
Please be as detailed as possible
What is the risk of constructing a harbor which will be unprotected from wave attack during its construction.
Consider a house into which radon is emitted through cracks in the basement. The total volume of the house is 650 m3 (assume that the volume is well mixed throughout).
Coal has about 5% sulfur. How many pounds of sulphur would be emitted from coal-fired power plants in the united states in 3 years? (each year. U.S electricity production in about 0.28 x 1012 watts, and coal has an energy content of about 30 x 106 J/..
State the basic difference between the general method of slices and the bishop method of slices. b.)State the basic difference between the bishop and fellenius method of slices
A pneumatic-tired tractor with a 354 - hp engine has a maximum speed of 3.6 mph in 1st gear. Determine the max. rimpull of the tractor in each gear if the engine effieicency is 91%.
The water table is 7m below the surface of the sand. The saturated unit weight of the sand is 19kN/m3 and that of the clay 20kN/m3; the unit weight of the sand above the water table is 16kN/m3.
A square footing 0.3 m by 0.3 m is placed on the surface of a dense cohesionless sand (unit weight = 18.2 KN/m^3) and subjected to a load test. If the footing fails at a load of 13.8 KN, what is the value of ? (degree) for the sand?
The homogeneous gate shown consists of one quarter of a circular cylinder and is used to maintain a water depth of 4m. That is, when the water depth exceeds 4m, the gate opens slightly and lets the water flow under it. Determine the weight of the gat..
Two level sections of an east-west highway (G = 0) are to be connected. Currently, the two sections of highway are separated by a 4000-ft (horizontal distance), 2 % grade. The westernmost section of highway is the higher of the two and is at eleva..
Show that the head loss in a hydraulic jump formed in a rectangular channel may be expressed as : change in E =(y2 - y1)^3/(4y1*y2) where y1 and y2 are depth of flow before and after jump.
Assuming uniformly decelerated motion, determine the velocity and acceleration of point C of the belt, (a) immediately before the power is turned off. (b) 9 s later.
A 200lb homogeneous gate of 10ft width and 5ft length is hinged at point A and held in place by 12ft long brace as the bottom of the brace is moved to the right the water level remains at the top of the gate.
