tank contains 250 liters of fluid in which 20 grams of salt is dissolved. Pure water is then pumped into the tank at a rate of 5
eimsori [14]

Solution :

Given data :

c_{in} = 1 g/L

r_{in} = 5 L/min

r_{out} = 5 L/min

$v_0$ = 250 L

A_0 = 20 g

∴ r_{net} = r_{in}- r_{out}

         = 5 - 5

          = 0

c_{out} = \frac{A}{250} \ g/L

Now, \frac{dA}{dt}=(r_{in} \times c_{in}) - (r_{out} \times c_{out})

$\frac{dA}{dt} = 5-5\left(\frac{A}{250}\right)$

\frac{dA}{dt}+5 \left(\frac{A}{250}\right) = 5

\frac{dA}{dt}+5 \left(\frac{A}{250}\right) = 5 \text{ with} \ A_0 = 20

Integrating factor = exp(5 t/250)

Therefore,

A \times \exp (5t \ /250) = \text{integral of}\ 5 \times \exp (5t / 250) + C

Put A_0=250+C

C = -230

A \times \exp(5t/250) = 250 \exp(5t/250) + (-230)

A(t) = 250-230 \exp(-5t/250)

A(t) = 250-230e^{\left(\frac{-t}{50}\right)} \ g
