Concept explainers
Chemical Mixture A tank contains 20 gallons of a solution composed of 90% water and 10% alcohol. A second solution containing half water and half alcohol is added to the tank at the rate of 2 gallons per minute. At the same time, the well-stirred solution is withdrawn at the same rate, as shown in the figure.
(a) Find the amount y (in gallons) of alcohol in the solution as a function of t by solving the differential equation
(b) Find the amount of alcohol in the tank after 10 minutes.
