Chapter 7, Problem 7.22P

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

A1.4- Determine the factored moment resistance for the flanged beam (simply supported) shown in Figure 4. Given: Beam span L = 8m fc = 25MPa fy=400MPa As = 3-35M *350* mm 1.5 m Figure 4 *350* mm -60mm
A2.3- a simply supported reinforced concrete beam of rectangular cross-section is shown in Figure 3. The beam supports a uniform dead load of 20 kN/m (excluding the beam self-weight) and a uniform live load of 20 kN/m. The beam width is restricted to 400 mm. The maximum aggregate size is 20 mm. We are using 10M bars for stirrups and 25M bars for tension steel. Concrete is type N with f'c = 35 MPa and fy = 400 MPa. The beam needs to have 2hr fire rating. Design the beam for the given load, considering the reinforcement ratio p < 0.5 pb Figure 3 WDL = 20 kN/m WLL= 20 kN/m 8.0 m
A2.2- For the given reinforced concrete section shown in Figure 2, a) Determine the balanced reinforced amount for this section; b) Calculate the ultimate moment resistance of the section if As = 8-20M. What is the mode of failure? c) Calculate the ultimate moment resistance of the section if As = 8-30M. Determine the strain in the steel reinforcement. Given: fc 30 MPa fy = 400 MPa 625 mm 500 mm + + *. 400 mm Figure 2
