Question

consider a tank used in certain hydrodynamic experiments. after one experiment the tank contains 200L of a dye solution concentration of 1g/L. to prepare for the next experiment, the tank is to be rinsed with fresh water flowing in at a rate fo 2L/m the well stirred solution is flowing out at the same rate. Find the time that will elapse before the concentration of dye in the tank reaches 1% of its original value.

Answer 1

Wow nice and tricky question

Answer 2

i have it set up like dQ/dt = 2 - 2Q/200, but iam i right?

Answer 3

and then i will need to differentiate.

Answer 4

yes

Answer 5

can you do it
