A tank contains 365 gallons of water and 50 oz of salt. Water containing a salt concentration of
1/6(1 + 1/4 sin t)
oz/gal flows into the tank at a rate of 8 gal/min, and the mixture in the tank flows out at the same rate.
The long-term behavior of the solution is an oscillation about a certain constant level.

a) What is this level?
b) What is the amplitude of the oscillation?

A tank contains 200 gallons of water that has 5 lbs of salt already in it. A brine containing .5 lbs of salt per gallon is entering the tank at a rate of 2 gal min , and the well stirred mixture exits the tank at the same rate. What is the concentration of salt in the tank after 5 minutes?

A tank is filled to capacity with 400 gallons water containing 30 lbs of salt. Brine...

A tank is filled to capacity with 400 gallons water containing 30 lbs of salt. Brine containing 2 lbs of salt per gallon is pumped into the tank at a rate of 3 gallons per minute. The well mixed solution is pumped out at rate of 3.5 gallons per minute. Determine the differential equation of the model and solve for an equation relating amount of salt in tank at time t. Determine the time until the tank is empty.

A tank contains 40 lb of salt dissolved in 400 gallons of water. A brine solution is pumped into the tank at a rate of 4 gal/min; it mixes with the solution there, and then the mixture is pumped out at a rate of 4 gal/min. Determine A(t), the amount of salt in the tank at time t, if the concentration of salt in the inflow is variable and given by cin(t) = 2 + sin(t/4) lb/gal. A(t) =
