5. A small swimming pool is contaminated with a pesticide from the nearby agricultural run-off with a concentration of C. Initially, at t = 0, a special faucet opens pouring in clean water at a constant rate Q. The drain is also simultaneously opened so the pool is draining at rate Q as well. Volume of the pool is constant. a) Derive an equation to predict the pesticide concentration for t > 0. b) What is the steady-state pesticide concentration in the pool?
