A porous block attached to air line emits tiny air bubbles

Reference no: EM13256221

A porous block attached to an air line emits tiny air bubbles(diameter=0.15mm, 21% O(xygen) at the bottom of a fish tank filled with water at 25 celcius. The absolute pressure in the bubbles at the bottom of the tank is 1.07x10^6 g/cm per s^2 when they are released. They reach their terminal upward velocity almost instantly, since they enter the tank at nearly this velocity.

Find the rate of oxygen transfer from one of these bubbles to the water. The concentration of oxygen already in the water can be neglected. (Diffusion coefficient of oxygen in H2O = 2x10^-5 cm^2/sec.
