Consider a tank filled initially with 10L of water. Saline (2% w/v NaCl)is added at a rate of 2L/hr, where it is mixed thoroughly by an ideal mixture. At the same time, the contents of the tank are allowed to drain out, also at the rate of 2L/hr. How long does it take for the concentration of salt in the outflow stream to reach a value of 0.25% (w/v)?
