  2. Tip #1: Assume that the filling rate or the emptying rate for each pipe is constant Question: Pipe A can fill the tank in 20 hours while Pipe B alone can fill it in 30 hours and Pipe C can empty the tank in 40 hours. If all the pipes are opened together, in how long will the tank be full? Solution: Let the capacity of the tank be C liters Fill rate of A, Fa = C/20 liters per hr Fill rate of B, Fb = C/30 liters per hr Fill rate of C, Fc = - C/40 liters per hr[Negative since this pipe is emptying the tank] Let t be the time taken to fill the tank to maximum capacity. t x [Fa + Fb + Fc] = C => t = 120/7 hrs Question: A pump can fill a tank with water in 2 hours. Because of a leak, it took 2.5 hours to fill the tank. If the pump is turned off, how long will it take to empty the tank? Solution: Fill rate of pipe, Fp = C/2 liters per hr Let the fill rate of the leak be FL 2.5 x [Fp + FL] = C => FL = - C/10 With the pump turned off, it would take 10 hrs for the leak to empty the tank.
