4. A confined horizontal aquifer of 20 m thickness and permeability K = 22 m/day, connects two reservoirs M and N situated 2 km apart. The elevations of the water surface in the reservoirs M and N measured from the top of aquifer are 30 m & 10 m respectively. If the reservoir M is polluted by a contaminant suddenly, how long will it take the contaminant to reach the reservoir. N. Assume the porosity of aquifer n=0.26
