Question
Transcribed Image Text:A tank with a capactiy of 500 gal originally contains 200 gal of water with 100 lb of salt in
solution. Water containing 1 lb of salt per gallon is entering at a rate of 3 gal/min. Find
the amount of salt in the tank at any time prior to the instant when the solution begins to
overflow. Find the concentration (in pounds per gallon) of salt in the tank when it is on the
point of overflowing. Compare this concentration with the theoretical limiting concentration
if the tank had infinite capacity.
