set up a differential equation to represent 2 tons of salt entering a 20 ton tank of water each minute while 2 tons of the mixture are drained each minute
The discussion focuses on modeling the flow of salt and water in a tank using a differential equation. The equation represents 2 tons of salt entering a 20-ton tank of water each minute, while 2 tons of the mixture are drained each minute. The amount of salt, S, is defined as S = S_0 + \dot S × t, where \dot S is the constant rate of salt addition. The equation provided is \(\frac {d}{dt} \frac {S^2 + W^2}{S+W} = \dot S\).
