Problem

Suppose a 50-gallon tank contains a volume V0 of clean water at time t = 0. At time t = 0,...

Suppose a 50-gallon tank contains a volume V0 of clean water at time t = 0. At time t = 0, we begin dumping 2 gallons per minute of salt solution containing 0.25 pounds of salt per gallon into the tank. Also at time t = 0, we begin removing 1 gallon per minute of salt water from the tank. As usual, suppose the water in the tank is well mixed so that the salt concentration at any given time is constant throughout the tank.

(a) Set up the initial-value problem for the amount of salt in the tank. [Hint: The initial value of V0 will appear in the differential equation.]


(b) What is your equation if V0= 0 (the tank is initially empty)? Comment on the validity of the model in this situation. What will be the amount of salt in the tank at time t for this situation?
