A well casing with a radius of 2 in. is installed through a confining layer into a formation with a thickness of 10 ft. A screen with a radius of 2 in. is installed in the casing. A slug of water is injected, raising the water level by 0.5 ft initially. Given the following recorded data for head decline, find the values of T and K for this aquifer, using Hvorsev analysis. Assume H0 = 0.0 and H = 0.5 ft after injection.
Assume L = 15 ft.
