Q2) A canal of trapezoidal section has bed width of 8 m and bed slope of 1 in 4000. If the depth of flow is 2.4 m and side slopes of the chamel are 1 horizontal to 3 vertical, determine the average flow velocity and the discharge carried by the channel. Also compute the average shear stress at the channel boundary. Take value of Chezy's constant = 55. Q3) 6.11. A power canal of trapezoidal section has to be excavated through hard clay at least cost. Determine the dimensions of the channel, given, discharge equal to 14 m/s, bed slope 1:2500 and Manning's N = 0.02.
Q1) A triangular gutter, whose sides include an angle of 60°, conveys water at a uniform depth of 250 mm. If the discharge is 0.04 m/s, determine the gradient of the trough. Use the Chezy's formula assuming that C = 52. с B 30° 250 m 60°
Q5) An aquifer of 20 m average thickness is overlain by an impermeable layer of 30 m thick- ness. A test well of 0.5 m diameter and two observation wells at a distance of 10 m and 60 m from the test well are drilled through the aquifer. After pumping at a rate of 0.1 m²/s for a long time, the following drawdowns (amount that head is lowered from the initial posi- tion) are stabilized in these wells: first observation well, 4 m; second observation well, 3 m. Determine the hydraulic conductivity of the aquifer and the drawdown in the test well. determine the time of travel of groundwater from the observation well at a distance 60 m to the pumped well if the porosity of the aquifer is 0.3.

Answer #1

Complete solution for question 1 is given below.

Sohition : Given d = 250 mm A a 0.04 m/ 250 c = 52 3 • From figure tan 38 = Ac AC oc 250 . AC = 144.344 mm 6. AB = 288.68 mmHydraulic mean depth A 62.5 mm Р ma 0.0625 m A 0.0369 m² * Chezys equation is given by Q = AC mi 0.04 = 0.0369 x 52 x v 0.06
