1. a confined aquifer with porosity of 0.15 is 30 m thick. the potentiometric surface elevation at two observation wells 1000 m apart are 52.35m and 56.90m. if the horizontal hydraulic conductivity of the aquifer is 25m/day, determine the
(i) flow rate per unit width of the aquifer. (ii) specific discharge (iii) average linear velocity of the flow assuming steady unidirectional flow. how long would it take for a tracer to travel the distance between the observation wells.
2. A field sample of an aquifer is packed in a test cylinder. the cylinder has a length of 120cm and a diameter of of 12cm. the field sample with a porosity of 0.24 is tested under a constant head difference of 160cm with water at 10-degrees centigrade. if the estimated hydraulic conductivity of the sample is 30m/day, calculate
a. the expected total discharge (b.) the specific discharge (c) the average flow velocity (d) the hydraulic gradient along the cylinder. (e) what should be the range of water temperature for Darcy's law to be applicable if the median diameter of the sample is 2.2mm.
