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 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?
