. A design for a rectangular weir to be placed in an open
channel is shown in the figure. In the proposed design, the volume
flow rate is 900 cfs, b = 15 ft and h = 5 ft. A 1/20 physical model
is constructed using water at the same temperature and pressure as
will be used in the prototype. What should the flow velocity be in
the model to ensure dynamic similarity?

2. Design a trapezoidal channel to pass a discharge of 10m3/s and the channel will be excavated through rock by blasting. The topography in the area is such that a bottom slope of 1 in 4000 will be suitable. Assume that n = 0.030 and select a value for the side slope, Z, as 1 horizontal to 4 verticals. Sketch the diagram for all calculated dimensions.

DESCRIPTION T-shaped open channel has two sub-channels more rough surfaces than the main channel. If the longitudinal slope of the channel is 0.0004 and y-2.5m, y=1m, b;=5m, b -8m, n, -0.018m, 12-0.036m. ASKED • find the total discharge flowing in the channel DESIGN • If this channel falls into a rectangular cross-section at the downstream side, and it is planned to have normal flow depth, y=1.5m, calculate the required base width, b. • If there is a 40cm smooth step...

An aqueduct is an open water channel on top of a support bridge. The bridge maintains a shallow slope to use gravity to carry water (p = 1000 kg/m”, u = 10-3 Pa.s) over long distances from a reservoir to a community. The aqueduct shown below has a rectangular cross section, as shown in section A-A, with width W = 1.2 m. The water level in the duct is a constant d = 1 m over the entire length of...
