Section 1.1 Direction Fields: Problem 12 (1 point) A pond contains 1000 L of pure water and an uknown amount of an undesirable chemical. Water contaninig 0.06 kg of this chemical per liter flows into the pond at a rate of 5 L/h. The mixture flows out at the same rate, so the amount of water in the pond remains constant. Assume that the chemical is uniformly distributed throughout the pond. Let Q(t) be the amount of chemical (in kg) in the pond at time t hours. (a) Write a differential equation for the amount of chemical in the pond? at any time time (enter Q for Q(t): dQ/dt = (b) How much chemical will be in the pond after a long time? Q_inf = (kg) (c) Does the limiting value in part (b) depend on the amount that was present initially? no

Step 1
Water with 0.06 kg/L of the chemical flows into the pond at a rate of 5 L/h. So, the rate of the chemical flowing in is 0.06 kg/L * 5 L/h = 0.3 kg/h. Show moreā¦

A pond initially contains 6,000,000 gal of water and an unknown amount of an undesirable chemical. Water containing 0.04 grams of this chemical per gallon flows into the pond at a rate of 200 galh. The mixture flows out at the same rate, so the amount of water in the pond remains constant. Assume that the chemical is uniformly distributed throughout the pond. (a) Write a differential equation for the amount of chemical in the pond at any time. Let q(t) denote the amount of chemical in the pond at time t. Use q as q(t). Do not use thousands separator in the answer field. (b) How much of the chemical will be in the pond after a very long time? Does this limiting amount depend on the amount that was present initially? q= grams The limiting amount (Does, Does not) depend on the amount that was present initially.

The pond initially contains 4,000,000 gal of water and an unknown amount of an undesirable chemical. Water containing 0.04 grams of this chemical per gallon flows into the pond at a rate of 100 gal/h. The mixture flows out at the same rate, so the amount of water in the pond remains constant. Assume that the chemical is uniformly distributed throughout the pond. (a) Write a differential equation for the amount of chemical in the pond at any time. Let q (t) denote the amount of chemical in the pond at time t. Use q as q (t). Do not use thousands separator in the answer field. (b) How much of the chemical will be in the pond after a very long time? Does this limiting amount depend on the amount that was present initially?

A pond initially contains 8,000,000 gal of water and an unknown amount of an undesirable chemical. Water containing 0.04 grams of this chemical per gallon flows into the pond at a rate of 100 gal/h. The mixture flows out at the same rate, so the amount of water in the pond remains constant. Assume that the chemical is uniformly distributed throughout the pond. (a) Write a differential equation for the amount of chemical in the pond at any time. Let q(t) denote the amount of chemical in the pond at time t. Use q as q(t). Do not use thousands separator in the answer field. dq/dt = 80000 grams/hour (b) How much of the chemical will be in the pond after a very long time? Does this limiting amount depend on the amount that was present initially? q = 40,000 grams
