At time t=0 a tank holds 550 gallons of water with 100 pounds of dissolved salt. An input pipe brings in solution at 8 gallons per minute at a concentration of 2 pounds per gallon. An output pipe carries away solution at 2 gallons per minute. Find how much salt is in the tank after 45 minutes.

At time t = 0 a tank contains 25lb of salt dissolved in 100
gallons of water. assume that water containing 2lb salt/gallon
enters the tank at a rate of 5 gal/min and the well-stirred
solution is leaving the tank at the same rate.
solve for Q(t) [Amount of salt in tank at time t ]

A 200 gallon tank initial contains 100 gallons of water and 20
pounds of dissolved salt. Brine solution begins to enter the tank
at the rate of 2 gal/min with a salt concentration of 2 lb/gal. The
well mixed solution leaves the tank at the rate of 1 gal/min. Find
the amount of salt inside the tank 50 minutes after the process
starts?

A 2 liter tank of water contains 3 grams of salt at time t = 0
(in minutes). Brine with concentration 3t grams of salt per liter

Suppose that a large mixing tank initially holds 500 gallons of
water in which 50 pounds of salt have been dissolved. Another brine
solution is pumped into the tank at a rate of 3 gal/min, and when
the solution is well stirred, it is then pumped out at a
slower rate of 2 gal/min. If the concentration of the
solution entering is 2 lb/gal, determine a differential equation

Suppose that a large mixing tank initially holds 400 gallons of
water in which 65 pounds of salt have been dissolved. Another brine
solution is pumped into the tank at a rate of 6 gal/min, and when
the solution is well stirred, it is pumped out at a slower rate of
5 gal/min. If the concentration of the solution entering is 3
lb/gal, find the amount of salt in the tank after 10 minutes.
