Question 4 BA rectangular sharp crested weir is to be constructed in a testing station with a small stream inwhich the discharge varies from 50 liters/s and 1250 liters/s. Find the suitable length of theweir, if the minimum head to be measured is 50 mm and the maximum head on it does notexceed one-third of its length.

If you have any questions let me know in the comment box immediately thankyou.

For the soils that are classified by the following AASHTO symbols, what would be the most likely USCS symbols? (Reference: Liu, 1970) Gravels sands: A-l-a, A-l-b, A3, A-2-4, A-2-5, A-2-6, A-2-7 Fines: A-4, A-5, A-6, A-7-5, A-7-6
A hydrometer test has the following result: Gs = 2.65, temperature of water = 26 C, and L = 10.4 cm at 45 minutes after the start of sedimentation (see Figure 2.25). What is the diameter D of the smallest-size particles that have settled beyond the zone of measurement at that time (that is, t = 45 min)?

Refer to Figure 7.24. The following data were collected during the field permeability measurement of a confined aquifer using a pumping test. Determine the hydraulic conductivity of the permeable layer. Use Eq. (7.49). Thickness of the aquifer, H = 4.5 m Piezometric level and radial distance of the first observation well: h1 = 2.9 m; r1 = 17.8 m Piezometric level and radial distance of the second observation well: h2 = 1.8 m; r2 = 8.1 m Rate of discharge from pumping, q = 0.5 m3/min
Redo Problem 12.30 assuming that the water table coincides with the top of the fill and that sat(fill) = 19.8 kN/m3. If the other quantities remain the same, what would be the downward drag force on the pile? Assume ' = 0.5fill. 12.30 Figure 12.49a shows a pile. Let L = 15 m, D (pile diameter) 305 mm, Hf = 3 m, fill = 17.5 kN/m3, and fill = 25°. Determine the total downward drag force on the pile. Assume that the fill is located above the water table and that = 0.5fill.
