Problem 1: A well is dug in the ground. The ground surface elevation is 1340 ft. The water surface level in the well has an elevation of 1319 ft. The bottom of the well has an elevation of 1298 ft. What are the hydraulic head, pressure head, and pressure in the aquifer at the location of the well? Problem 2: The intrinsic permeability of a soil sample is 3.5×10 ft². What is the water discharge per unit width, in cubic ft per day, through a confined aquifer of similar soil properties for hydraulic head difference of 0.51 ft over a length of 750 ft? The water temperature through the soil is 50°F and the porosity of the soil is 0.30. The average depth of the aquifer is 35 ft. Also, find the time in days the water will take to move 500 ft. Problem 3: Find the hydraulic conductivity of the soil sample shown below. The porosity of the soil sample is 0.31. The piezometers readings are W₁ = 20 cm and w₂ = 28 cm. The discharge is 0.55 liters/day and Ax 65 cm. The soil sample is contained in a tube of 15-cm diameter, where = 42 degrees. Find the time it takes for a water particle to travel the length of the sample.
