B. (20 A) Water flows under a sluice gate discharges into a rectangular plain stilling basin. Design suitable stilling basin with drawing and all necessary dimensions for the following condition: q = 21 m / sec. m, HL = 2.7m, width of basin = 13m.

(Single pipe - determine pipe diameter) Water is to flow at a rate of 1.0 m³/s through a rough concrete pipe (ε = 5 mm) that connects two ponds. Determine the pipe diameter if the elevation difference between the two ponds is 10 m and the pipe length is 1000 m. Neglect minor losses. D= 0.783 m

Quo Put a Circle around the CORRECT Answer 1- Given: *Length of Secondary open drain Lopen = 2400 (m). *Tile Drains Spacing, S = 80 (m). * Flow Rate of Secondary Open Drain, Qopen = 5580 (m³/d). (a) Qrile 200 (m³/s) (b)QTile = 300 (m³/s) (c) Qrile = 186 (m³/s) 2- Given: * Effective depth of the impermeable layer below Tile Drain level, *de = 12 (m). *Hydraulic conductivity of soil layer located above Tile Drains level, Ka = 6 (m/d). * Hydraulic conductivity of soil layer located below Tile Drains level, Kb = 0.5 (m/d). * Maximum height of W.T. above Tile Drains level at mid-distance Ho = 0.8 (m) *Drain Spacing S = 45 (m) Drainage Coefficient R. is: (a) 0.001 (m of water/d) (b) 0.015 (m of water/d) (c) 0.026(m of water/d) P-12 3- An agricultural farm is cultivated by mixed crops. There is no drainage system in farm. The available data are: *Leaching Requirements of the farm, LR = 37% *Depth of Irrigation Water, (dw)i = 0.081 (m of water/Irrigation) *Depth of drained water (dw) is: (a) 1…

Design a trapezoidal S.A.F stilling basin (Full design: chute blocks, baffle blocks, end sill, and side walls) and draw a full details of a single chute block and baffle block using the given data (Note: use the attached chart): Flow discharge per unit width (q)= 24 m²/sec. Head loss throughout the basin (HL) 1.5 m. Ex-7.2 m. Basin width at the end sill (BE)- 20 m. Tail water depth-6 m. Slope of the glacis- 30°. Flaring (1:2) 1:6.
