A concrete-lined channel is used to convey water flow between Point A atsurface elevation of 510 m and point B at surface elevation of 508 m above sea level over adistance of 2 kilometers. The surface roughness coefficient of the concrete is 0.012. The flowconveyed by this channel in m³/s is most nearly:A. 70B. 105C. 150D. 1654m5 m4m

2.Water flows through a rectangular channel with a width b = 2 m and a height (Pw) = 1 m, the flow rate ranges from Qmin = 0.02 m^3/s and Qmax = 0.60 m^3/s. This flow rate is measured using Rectangular sharp-crested weir Triangular sharp-crested with = 90^o Broad-crested weir Plot onto the graph Q = Q(H) for each type of weir and give your analysis which type of weir is most appropriate to apply
Uniform water flow in a wide brick channel of slope 0.02°moves over a 10-cm bump as in Fig.. A slightdepression in the water surface results. If the minimumwater depth over the bump is 50 cm, compute (a) thevelocity over the bump and (b) the flow rate per meterof width.
A multipurpose reservoir with a surface area of 1 km² is being designed for Gibson, TN. The daily average inflow from a nearby stream is 0.05 m³/s. Annual precipitation averages 1400 mm/yr and losses to evaporation and seepage to groundwater are expected to be 500 mm/yr. A minimum daily release of 0.01 m³/s is required to protect downstream fisheries. Assuming the volume of the lake is 107,000 m³, how long will it take to fill the reservoir?

1. In a steady spatially varied flow in a prismatic open channel, the (a) depth does not change along the channel length (b) discharge is constant along its length (c) discharge varies along the length of channel (d) discharge varies with respect to time.
7. A long triangular open channel with two different side slopes, these are: 2:1 and 3:1 (H: V). The Manning coefficient is 0.014. The longitudinal bed slope =0.004, this channel is converted to the best economic section by using the same amount of material at depth 1.5m in the old section. The old and new flow discharges in m3/s (respectively) are: 9.9 & 57.5 29.8 & 67.3 20.5 & 14.5 19.9 & 37.3 None
