A reservoir contains 100 million gallons of water. On the first of January, the EPA measures the amount of a pollutant in the reservoir and determines that there are C pounds of pollutant. The reservoir is fed by a polluted stream that brings in 1 million gallons of water per day. This stream water contains the pollutant at a concentration of 0.00002 pounds of pollutant per gallon. At the same time, reservoir water escapes through a channel to the ocean in such a way that the amount of water in the reservoir stays fixed. Let P(t) denote the amount of pollutant in pounds the reservoir at time t.

A )How many pounds of pollutant enters the reservoir per day ?

B )How many pounds of pollutant exits the reservoir per day?

C )Write a differential equation that describes the rate that the amount of the pollutant present in the reservoir is changing. You should include any initial conditions that the pollutant satisfies, but you do not need to solve the differential equation

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 100 gallon tank initially contains 10 gallons of fresh water. At t=0 a brine solution containing 1 pound of salt per gallon is poured into the tank at the rate of 4 gal/min., while the well-stirred mixture leaves the tank at the rate of 2 gal/min. Find the amount of salt in the tank at the moment of overflow. Enter answer as numerical decimal correct to two decimal places. pounds.

initially a large tank with a capacity of 300 gallons contains 150 gallons of clean water. A solution of salt with a concentration of 2 lb / gal flows into the tank at a rate of 50 gal / min. The solution is perfectly well mixed while the solution is extracted at a rate of 25 gal / min. Find: a) the amount of salt in the tank at the time it is filled (in pounds) b) the speed at...

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?

Your boss asked to analyze a system that initially contains 3,000 gallons of water that is contaminated with 53 lbs of arsenic. He wants you to reduce the concentration of the arsenic down to 10 mg/L, which is the standard that the US Environmental Protection requires for your company to be able to bottle and sell the water. You have a 1 hp pump that will allow you to move 17 gallons/minute of water into the well-mixed tank with the...
