A tank contains initially 2500 liters of 50% solution. Water enters the tank at the rate of 25 iters per minute and the solution

sergejj [24]

Answer:

Percentage of solution=32. 96%

Explanation:

Given that initially tank have 50% solution.It means that amount of solution=0.5 x 2500 =1250 lts

Lets take the amount of solution at time t = A

So

$\dfrac{dA}{dt}=rate\ in\ solution -rate\ out\ solution$

$\dfrac{dA}{dt}=concentration\times rate\ in\ of\ water -concentration\times rate\ out\ of\ water$

$\dfrac{dA}{dt}=0\times 25-\dfrac{A}{2500}\times 50$

$\dfrac{dA}{dt}=-\dfrac{A}{50}$

Now by integration

$\ln A=-\dfrac{1}{50}t+C$

Where C is the constant

Given that at t=0 ,A=1250

So $C=\ln 1250$

$\ln A=-\dfrac{1}{50}t+\ln 1250$

When t=20 min

$\ln A=-\dfrac{1}{50}\times 20+\ln 1250$

A=837.90

So percentage of solution after 20 min

$=\dfrac{1250-837.9}{1250}\times 100$

Percentage of solution=32. 96%
