9. A tank initially contains 80 gallons of sugar water having a sugar concen- tration of 5 pounds per gallon. A sugar solution with a concentration of 4 pounds per gallon is poured into the tank at a rate of 6 gal per minute and is thoroughly mixed at the same time. A drain is opened at the bottom of the tank so that the thoroughly mixed sugar water is leaving the tank at the same rate of 6 gal...

A tank with a capacity of 400 gallons originally contains 100 gallons of water with 25 pounds of salt in solution. Water containing 1/2 pound of salt per gallon is entering at a rate of 4 gallons per minute, and the mixture is allowed to flow out of the tank at a rate of 1 gallon per minute. FIND the amount of salt in the tank at any time prior to the instant when the solution begins to overflow.

13. A 600 gallon capacity tank initially contains 50 pounds of salt dissolved in 100 gallons of water. Water containing 2 pounds of salt per gallon enters the tank at a rate of 6 gallons per minute (assume the salt is evenly distributed throughout the water in the tank). Water is drained from the tank at a rate 4 gallons per minute. How many pounds (rounded to 1 decimal place) of salt will be in the tank when the tank...

A tank originally contains 100 gallons of fresh water. Water containing lb of salt per gallon is poured into the tank at a rate of 2 gallons per minute, and the mixture is allowed to leave at the same rate. After 10 minutes the salt water solution flowing into the tank suddenly switches to fresh water flowing in at a rate of 2 gallons per minute, while the solution continues to leave the tank at the same rate (a) Write...

A tank contains 150 gallons of brine whose salt concentration is 2 pounds per gallon. Three gallons of brine whose salt concentration is 4 pounds per gallon flow into the tank each minute. At the same time 3 gallons of the mixture flows out each minute. If the mixture is kept uniform by constant stirring, find the salt content of the brine as a function of the time t. Approximately how long will it take until there are 240 pounds...

2. A tank initially contains 100 gallons of salt solution in which 20 pounds of salt is dissolved. Starting at time 0, a solution containing 3 pounds of salt per gallon flows into the tank at a rate of 4 gallons per minute. The mixture is kept uniform by stirring and the well-mixed solution simultancously flows out of the tank at the same rate. Determine the amount of salt in the tank after 10 minutes, when the amount of salt...
A tank initially contains 500 gallons of water in which 40 pounds of salt is initially dissolved in the water
A tank initially contains 500 gallons of water in which 40 pounds of salt is initially dissolved in the water. Brine (a water-salt mixture) containing 0.4 pounds of salt per gallon flows into the tank at the rate of 5 gal/min, and the mixture (which is assumed to be perfectly mixed) flows out of the tank at the same rate of 5 gal/min. Let y(t) be the amount of salt (in pounds) in the tank at time t. a) Set up...
