In a solar pond the salt is placed at the bottom of the pond 1.5 m deep. The surface is flushed constantly so that the concentration of salt and the top of layer is zero. the salt concentration at the bottom layer is 5 kg mol/m^3. Calculate the rate at which salt is washed off at the top at steady state condition per m^2. Take D_{ab=1.24*10^-9}
m^2/s . Total concentration= 55.55kg mol/m^3.
