Extracted text: Two component system-continued dilution of salt solution Problem: A tank holds 100 litre of a salt-water solution in which 4 g of salt are dissolved. Water runs into the tank at the rate of 5 litre/min. and the salt solution overflows at the same rate. If the mixing in the tank is adequate to keep the concentration of salt in the tank uniform at all times, (a)Write a differential mass balance equation on the tank and provide initial condition. (b)Solve the balanced equation to estimate how much salt is in the tank at the end of 50 minute? (c) Plot the concentration of salt in the tank as a function of time. [Assume that the density of the salt solution is essentially the same as that of pure water.]
