The hydraulic consultant for a municipality needs to develop plans for a rectangular channel with a 1 foot freeboard to provide water to the residents of the city. a) Determine the dimensions of the most efficient concrete channel section if the municipality's daily demand is 210 gallons per person and the channel loses 12% of its water to natural processes. The required water velocity in the channel is 7 feet per second. Find the channel width (ft), channel depth (ft), and channel bottom slope for the municipality that serves 1,500,000 people. b) Based on the channel design and requirements specified above, classify the flow in the channel. Justify your answer.
Determine the normal and critical tie rods in a trapezoidal channel with a stencil width b = 3m, slope k = 1 and bottom slope S = 0.002. The Manning's roughness coefficient is n = 0.035 when conveys a flow Q = 15 m3/s. Also calculate the Froude number to determine the flow regime.

Read the question carefully and give me both right solutions with clear calculations. A trapezoidal canal has one side vertical and the other sloping 1:1. The discharge is known to be 20 m3 /s at a mean velocity of 1.2 m/s. If the slope is to be minimum as possible, and n=0.015, (a) At what depth is it flowing in m? (b)What is the value of this minimum slope?

A bar screen is used to treat 10 MGD of menicipal wastewater. The vertical bars are 1.27 cm wide and 3.8 cm deep. The minimum allowable spacing for the bars is 2.4cm. The appoach channel carries the water at velocity of 0.381 m/s and is 1.07 m wide and 1.37 m deep. 1- detrmine the number of bar and spacing that should be used. 2- calculate the head loss through screen when it is clean (m). 3- it's estimated that the screen will remove 227 kg (wet basis) of screenings ber milion gallons of water treated. What will be the daily accumulation (kg and m^3) of the screening if the density of screening 100 kg/m^3.

A trapeziodal channel lined with grass (n = 0.027) has a bottom width of 4.25 feet, side slopes of 2 horizontal to 1 vertical, and a slope of 1.1 percent. Water is flowing at a depth of 2.35 feet. a) what is the discharge? b) what is the velocity?
1. In the upstream portion of a river, it has a rectangular channel 10m wide and 1.2m deep of water flowing with a mean velocity of 0.75 m/s. Determine the height (head H) in meters of a standard rectangular weir considered without contraction at the downstream portion, if the length of weir is half of the upstream channel width. 2. The river is measured through float method. It has a length marking of 10 meters. Trials were made for 10 times and tabulated the following recorded time in seconds: 12.4 15.5 16.8 17.1 14.9 14.4 16.6 17.2 18.2 15.8 Estimate the flow rate in m3/s of the river if the mean velocity is 75% of the maximum velocity at the top surface. The cross-section area of the channel is close to 15m x 2m.
