2. Design a pipe culvert to be provided for a highway embankment across a small valley having the following data: Top width of the embankment: 8 m Height of the embankment: 4 m Side slope: 1.5 H: 1 V Maximum discharge: 6 cu-m/s Slope of the valley: 1/100 Loading: IRC Class AA Also, draw a longitudinal section along the pipe.
H.W.: A concrete pipe culvert is to be constructed under road to carry a maximum discharge 9 m3/sec. If the length of pipe culvert 10m on slope 1/100 . Find the diameter of the pipe and draw the culvert between the change of discharge and the diameter.
water down a 8m wide spillway has a normal depth of 0.4. the spillway surface is finished concrete. manning coefficient is 0.012 the spillway slopeis0.1m. calculate the velocity v1 on the soillway an dthe flowrate q1.
A roadway-median channel is to be designed to carry a discharge of 0.60 m3/s on a slope of0.007. The trapezoidal channel will be lined with Bermuda grass that has an average heightof 15 cm, for which Manning’s n is 0.08. Considering efficiency and stability of thechannel, the ratio B/yn should equal 4 and the side slopes will be 3:1. Specify all otherdesign parameters for the channel (yn, B, FB, T, and Tchannel) in meters. Compute the velocity(m/s) and tractive force (kPa) at design capacity.
A corrugated metal, circular channel of diameter 3ft, carries a discharge of 6cfs at a normal depthof 1.2ft. Determine the ground slope required to generate the discharge.
1. Water flows in symmetrical trapezoidal channel lined with asphalt has a base width of 4.8 m and side slope of 3 horizontal to 1 vertical. It has a depth of flow of 1.36 m the channel drops 01 m vertically every 100 m. Using n= 0.015 A) Compute for the velocity of flow B) Compute for the critical velocity C) Compute for the discharge of the most efficient section if 0 = 30°, b=4.8m
Water flows in a 20000-m long smooth-asphalt trapezoidal channel at 55 m³/s with side slope of 2.5(H):1(V). Elevations at the beginning and end of channel are 400 m and 376 m, respectively. Analyse its efficient-channel section. (d)
Q8) Uniform flow occurs in a rectangular channel 2.5m wide at a depth of 900mm. If Manning’s “n” is 0.015 and the bed slope is 1/2000 what is the minimum height of hump in the bed which will produce critical flow
