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.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
