Question
A swimming pool is initially filled with 500 m3
of water with a chlorine concentration of 10
g/m3. Water containing 50 g/m³ of chlorine
flows into the pool at a
rate of 5 m3 per minute. The well-mixed water
in the pool is drained away at the same rate.
Find the amount of chlorine in the pool at any
time t > 0.
Select the correct response:
Q(t) = 25000 - 20000 e-t
Q(t) = 25000 – 20000 e-t/100
%3D
Q(t) = 25000 - 25000 e-t/100
Q(t) = 20000 – 25000 e-t/100
