Question 12 Water is flowing downwards through a vertical sand column as shown in Figure 6. The length of the column L 160 cm, the cross-sectional area A 220 cm2, the head difference Ah 130 cm (assume this head difference is constant). The sand in the column has a hydraulic conductivity k 25 m/d and the porosity n=0.32. Determine the steady state seepage velocity of soil.

5) A cylindrical plant pot (or soil pot) is filled to the top with new dry soil with porosity of 0.3. The radius of the pot is 0.25 m and the length is 0.75 m. The hydraulic conductivity of the soil is 1 m/day and the specific yield (Sy) of the soil is 0.25. 1) If the bottom of the pot is fully closed, what is the maximum volume of water (in m3) that can be stored in this new...

Question 5: (25 marks) A fully penetrating pumping well is located in a confined aquifer that can be considered to have an infinite extent in all directions. There is no recharge to the aquifer and no other pumping wells in the area. There are two observation wells located at 100 and 500 m, respectively, from the pumping wells. The aquifer and the pumping well have the following properties: Depth to top of aquifer: 50 m Aquifer thickness: 5 m Aquifer...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
