A 300 mm diameter well was penetrated in an oceanic island. The depth of the fresh water at a distance of 10 m was 8 m. The permeability of the aquifer was 1.2 m/day. An external recharge was percolate and infiltrate into the well with an average value of 120 mm/hr. Calculate the diameter of the island.

A 10 inches diameter well is drilled to the bottom of an unconfined aquifer. The water table is originally 500 ft above the bottom of the aquifer whose hydraulic conductivity is known to be 0.25 ft /day. If 100 gal/min is pumped from the well, what will be the equilibrium depth of the water in the well if the radius of influence is 1000 ft? How much drawdown should be expected at a distance of 250 ft from the well?

A spherical raindrop 3.1 mm in diameter falls through a vertical distance of 3550 m. Take the cross-sectional area of a raindrop = πr2, drag coefficient = 0.45, density of water to be 1000 kg/m3,and density of air to be 1.2 kg/m3. (a) Calculate the speed a spherical raindrop would achieve falling from 3550 m in the absence of air drag. (b) What would its speed be at the end of 3550 m when there is air drag?
