96. Flow Speed in a Channel The speed of water flowing in a channel, such as a canal or river bed, is governed by the Manning Equation, V = 1.486* pn Here V is the velocity of the flow in f/s; A is the cross- sectional area of the channel in square feet; S is the down- ward slope of the channel; p is the wetted perimeter in feet (the distance from the top of one bank, down the side of the channel, across the bottom, and up to the top of the other bank); and n is the roughness coefficient (a measure of the roughness of the channel bottom). This equation is used to predict the capacity of flood channels to handle runoff from heavy rainfalls. For the canal shown in the figure, A = 75 ft², S = 0.050, p = 24.1 ft, and n = 0.040. (a) Find the speed at which water flows through the canal. (b) How many cubic feet of water can the canal discharge per second? [Hint: Multiply V by A to get the volume of the flow per second.] 20 ft |5 ft –10 ft→|

1. A new town is being developed in a rural area of Costa Rica. Planners are projecting a population of about 2,000 people and a baseload electric energy demand for the town of 10MWe over the first 20 years. A nearby river flows from the rainforest region with a mean annual flow of 100m³/s. Over a 20 km distance upstream of the town site, the river has a change in elevation of 1,000 m. Seasonal variations in the river flow could be as large as a factor of ten above or below the mean flow. Is a hydro project using turbines with 80% efficiency feasible to meet the town's future energy needs? Discuss (2-3 sentences each) at least two associated impacts that planners also need to consider in the hydro project design.

A hydraulic jump is shown in figure below. The depth of flow z₂ after the hydraulic jump is 5 m larger than z₁. The total flow rate in the channel is 450 m³/s and the channel width is 50 m. The length / over which the jump occurs is 0.4 m. ax= If the depth, z₁, is 6 m then what is the average acceleration (ing's) of the liquid as is flows across the jump. 0.21 Hydraulic jump g's V₂

In gradually varied flow, the channel bottom, water surface, and EGL are parallel. Select one: O True O False

Pls answer asap I will give good ratings A jet of water flows from left to right and hits a splitter block, as shown in the figure. Some of the jet is diverted upwards and some of it downwards. The incoming jet has a velocity U1=U1=1.6 m/s and a cross-sectional area A1A1. The jet that is deflected upwards has a velocity U2=U2= 0.7 m/s, a cross-sectional area A2=A2= 11 cm22 and is at an angle θ2=θ2= 35oo with respect to the horizontal. The jet that is deflected downwards has a velocity U3=U3= 0.9 m/s, a cross-sectional area A3=A3=14 cm22 and is at an angle θ3=θ3= 25oo with respect to the horizontal. The density of water is ρ=ρ=1000 kg/m33.see diagram attached and answer - A-Find the cross-sectional area of the incoming jet (in cm22) B- Find the horizontal force on the block (in Newtons) (Note: remember to convert the area of the jets from cm22 to m22!)   c)The vertical force on the block is found to be FyFy. What velocity of the incoming jet (i.e. what value of u1u1) would be needed to…
