A 7-ft wide channel carrying water with a flow rate of Q =2 ft/s is metered by a V-notch weir with an included angle of 639 into a second unfinished concrete channel of 1/2 the width of the first, and a depth of 1/2 Y. If the vertex of the notch is 0.2 ft from the ground, please answer the following questiohs: A. What is the upstream velocity of the fluid (uniform approximation away from the weir)? B. What is...

Plot a rating curve of flow rate (Q,cfs) vs. water surface elevation (ft) for an ogee spillway that is 35 ft long with a design height of 3.5 ft as the water surface elevation changes from 54 ft to 58 ft (at least 2 data points per foot). You may assume the weir crest height is 53.5 ft. **Your water surface elevation is equivalent to the sum of your h (that changes) and your weir crest height (constant).**

Water flows steadily along a horizontal open channel of uniform width, over a broad-crested weir. The channel bed upstream from the weir (to the left) is d -0.75m above the channel bed downstream from the weir (to the right), as shown in the figure below. The volume flow rate per unit width is Q 6m2 s-1, and the downstream depth of the water is ћ2-d. Take the magnitude of the acceleration due to gravity as g 10ms-2. d - 0.75...

2. Water flow is measured by a 4 ft wide rectangular weir. The weir crest is 2.5 ft above the channel basement. The minimum and maximum water depths in the weir are measured as 0.4 ft and 2 ft, respectively. Calculate the minimum and maximum flowrates for a contracted rectangular weir with the length of 2 ft. (Note: Consider the relation between h and b/3, and choose appropriate equation to...

A pipe with an inner diameter of 8 inches (0.67 ft) carries water (ρ = 62.4 lbm/ft3, μ = 6.72 x 10-4 lbm/ft ⋅s) horizontally at a flow rate of 3.1 ft3/s. The pipe has been in service for a very long time, so the wall surface has become fairly rough (ε = 0.008 inches). The pipe is 1550 ft long. A) Calculate ΔP over the pipe length in psi B) Suppose the old pipe is now replaced with a...

Please show work.
Additional housing to accommodate 2000 persons is proposed for a residential area served by an existing 18-inch diameter vitrified clay sanitary sewer main constructed on a slope of 0.00412 ft/ft. To determine the feasibility of the proposed development, a 90° V-notch weir was placed in an existing manhole to measure the current flows. During peak hour flow conditions, the maximum head over the crest of the weir was measured at 16.5 inches. Note that the discharge over...
