A tank initially contains 50 liters of water with 15kg of salt mixed in. Salt water with concentration 1/3 kg/L runs in at the r
Nimfa-mama [501]

Answer:

13.57 kg

Step-by-step explanation:

Let the amount of salt in a tank be =\frac{salt in the tank}{volume of salt in the tank}

                                                         =    \frac{15}{50}

                                                         =  0.3 kg/L

The concentration of salt coming into the tank = 0.333kg/L

We know that the concentration of salt leaving the tank should be:

amount of salt in the tank/volume of tank = y(t)/50 L

rate of change of salt = rate in - rate out

\frac{dy}{dt} = 0.66 - \frac{y}{50}

solving the differential equation gives :

ln y = 0.66/y (t) - 0.02 t + C

Initial conditions, t= 0; y (0) = 15

then ln 15 = C

ln y = \frac{0.66}{y}t - 0.02t + ln 15

ln\frac{y}{15} = 0.02t

y = 15e( exp -0.02t)

the amount of salt in 5 mins will be:

y (t) = 15e(exp -0.02 (5)

      = 13.57 kg
