Setup a diﬀerential and solve the diﬀerential equation using Mathematica: Suppose water is added to a tank at 10 gal/min, but leaks out at the rate of 1/5 gal/min for each gallon in the tank. What is the smallest capacity the tank can have if the process is to continue indeﬁnitely?
The Attempt at a Solution
I know Q' = rate in - rate out. I'm clueless I have no idea to set this up. all I have are examples of actual mixing problems where something is being mixed like salt. i'm so confused. please help[/B]
