A 500 gal capacity tank initially contains 200 gal of water and 5 Ibs of salt pergallon. To reduce the concentration, water at the rate of 3 gal/min enters thetank and the thoroughly mixed solution flows out at the same rate. After 20min. the process is stopped and brine solution flows into the tank at the samerate of 3 gal/min and at a concentration of 2 Ibs/gal. The mixed solution flowsout at the rate of 2 gal/min.

A tank initially have 100 L with 50 g of dissolved salt. brine is pumped into the tank at a rate of 2 L/min carrying 2 grams of salt per liter. The well-stirred mixture is pumped out of the tank at a rate of 3 L/min. Find the concentration of the solution after 1 hour.
A tank initially holding 80 gals of fuid with 40 lbs of salt has two sources of fluid being pumped in. One source is pumping pure water in at 8 gal/min and the second source is pumping in a salt solution of 0.5 Ibs/gal at 2 gal/min. The tank is emptying at 10 gal/min. Find the amount of salt in the tank after 30 minutes?
