Question

A 100-gal tank is initially half full of pure water. Then water containing 0.1 lb/gal of salt is added at a rate of 4 gal/min. The tank contens are well mixed. water flows out of the tank at a rate of 2 gal/min untul the tank is full. Once the tank is full it overflows. Find the amount and concentration of salt in the tank as function of t for the first 2 hr.

Answer 1

Is this for differential equations?

Answer 2

yes..., this is one of applications of differential equations

Answer 3

Yeah, it's a mixing problem. Hmm..it's been a while since I've done one of these. Give me a minute to see if I can remember. lol

Answer 4

ok..., :)

Answer 5

\[\huge A'=R_{\text{In}}-R_{\text{Out}}\]Hmm let's see if we can figure this out..
