Hydrogeology Fetters (discharge per unit width)

13. Refer to Figure 4.19. The hydraulic conductivity of the aquifer is 14.5 m/day. The value of h1 is 17.6 m and the value of h2 is 15.3 m. The distance from h1 to h2 is 525 m. There is an average rate of recharge of 0.007 m/d. (A)What is the average discharge per unit width at x 5 0? (B)What is the average discharge per unit width at x 5 525 m? (C)Is there a water-table divide? If so, where is it located? (D)What is the maximum height of the water table?

Hydogeology Fetters (discharge, water-table elevation)

11. An unconfined aquifer has a hydraulic conductivity of 8.7 x 10-2 cm/s. There are two observation wells 597 ft apart. Both penetrate the aquifer to the bottom. In one observation well the water stands 28.9 ft above the bottom, and in the other it is 26.2 ft above the bottom. (A)What is the discharge per 100-ft-wide strip of the aquifer in cubic feet per day? (B)What is the water-table elevation at a point midway between the two observation wells? Show all work.

Hydrogeology Fetters (average linear velocity)

9. A confined aquifer is 8 ft thick. The potentiometric surface drops 1.33 ft between two wells that are 685 ft apart. The hydraulic conductivity is 251 ft/day and the effective porosity is 0.27. (A)How many cubic feet per day are moving through a strip of the aquifer that is 10 ft wide? Show all work. (B)What is the average linear velocity? Show all work.

Hydogeology Fetters (Darcy's law)

7. A sand aquifer has a median pore diameter of 0.232 mm. The fluid density is 1.003 x 103 kg/m3 and the fluid viscosity is 1.15 x 10-3 N-s/m2. If the flow rate is 0.0067 m/s, is Darcy's law valid? What is the reason for your answer? Show all work.

Lunar Eclipse; Solar Eclipse; Moon; Sun; Earth

Please do the attached question 3 only. Thanks. Problem (also attached) 3. Which of the below statements is false? - Total eclipse of the Sun arrives when the Moon precisely aligns itself between the Earth and the Sun and thus casts its shadow onto a narrow path across the Earth's surface ... - (see attachment for complete list of statements)
