A tank contains 80 gallons (gal) of pure water. A brine solution with 2 Ib/gal of salt enters at 2 gal/min, and the well-stirred mixture leaves at the same rate. Find (a) the amount of salt in the tank at any time, and (b) the time at which the brine leaving will contain 1 Ib/gal of salt.

2. Factory A produces a solution of 40% concentration of chemical Y at a rate of 7 kg/min, while factory B produces a solution of 20% concentration of chemical Y at a rate of 4 kg/min. Both solutions are fed into a mixer containing 60 kg of a 25% concentration solution of chemical Y. The mixture leaves the mixer at a rate of 10 kg/min. Assuming uniform mixing, what will be the concentration of chemical Y in the final solution after 20 minutes?2)
A manufacturing company has been experimenting with a new additive that is used to reduce polluting effluents from its production facility. Test results suggest that if no additive is used, pollution levels are 3000 parts per million (ppm). For each pound of additive used per week, pollution levels are reduced by 0.49 ppm. The additive costs $30 per pound. The reason for experimenting with the additive is that a government agency is conducting weekly air quality tests in the vicinity of the production facility. Regulations state that if pollution levels exceed 2000 ppm, a fine is imposed. The fine is $1000 for each ppm by which the pollution level exceeds the 2000 ppm limit. If the company has budgeted $80,000 per week to spend on the additive and any pollution fines, how much additive should be purchased each week for use by the company? What is the resulting amount that the company is willing to pay in terms of weekly fines?

Suppose that a healthy population of some species is growing in a limited environment and that the current population P0 is fairly close to the carrying capacity M0. You might imagine a population of fish living in a freshwater lake in a wilderness area. Suddenly a catastrophe such as the Mount St. Helens volcanic eruption contaminates the lake and destroys a significant part of the food and oxygen on which the fish depend. The result is a new environment with a carrying capacity M1 considerably less than M0 and, in fact, less than the current population P0. Starting at some time before the catastrophe, sketch a “before-and-after” curve that shows how the fish population responds to the change in environment.
Question 1 The CEO of Asempa farms limited is considering whether to plant this year’s yam with a fertilizer or go organic (i.e. without fertilizer). In case of using a fertilizer, 10kg of either the Platinum or Standard type fertilizer would be needed at the start of the planting year. The Platinum type is GH¢1000 per kilogram and could lead to a high yield of 30 tons or a moderate yield of 20 tons of yam at the end of the year. The Standard type is GH¢800 per kilogram and could also lead to a high yield of 15 tons or a moderate yield of 10 tons of yam at the end of the year. The Standard has fewer chemicals and would lead to tastier yam that sells for a higher price than that of Platinum. There is a probability of 0.7 that high yield would be recorded at the end of the year.Market price for yam is uncertain and depends on the type as well as the volume of yam on the market. Generally, a year of high yield results in higher volume whiles a year of moderate yield leads to moderate…
The work force of a certain factory is growing at rate of 2 per month while the average productivity of a worker is growing at a rate of 4 units per month. If the work force is currently 100 and the average productivity per month is 200 units, at what rate is the total productivity per month of the factory increasing?
Two pumps capable of delivering 100 hp to an agricultural application are being evaluated in a present economy study. The selected pump will only be utilized for one year, and it will have no market value at the end of the year. Pertinent data are summarized as given follows. If electric power costs $0.10 per kWh and the pump will be operated 4,000 hours per year, which pump should be chosen? Recall that 1 hp = 0.746 kW.
A 100L-capacity tank initially holds 80L of fresh water. A brine solution is poured into the tank at the rate of 4 L/hr, while the well-stirred mixture leaves the tank at the rate of 8 L/hr. If for the first three hours, the solution being poured into the tank contains 2g/L of salt, and for the succeeding hours, the solution being poured in contains 1g/L of salt, find the amount of salt in the tank when the tank starts to overflow.
Two large tanks, each holding 24 liters of a brine solution, are interconnected by pipesas shown in the figure. Fresh water follows into tank T1 at a rate of 6L/min and fluid is drainedout of tank T2 at the same rate; also 8L/min of fluid are pumped from tank T1 to tank T2 and2L/min from tank T2 to tank T1. The liquids inside each tank are kept well stirred. If, initially, thebrine solution in tank T1 contains 1 kg of salt and that in tank T2 contains 6 kg of salt, determinethe mass of salt in each tank at time t > 0
A tank contains 200 liters of brine in which there are 3 kg of salt per liter. It is desired to dilute this solution by adding brine containing 1 kg of salt per liter, which flows into the tank at the rate of 4 liters/min and the mixture, kept uniform by stirring, runs out at the same rate. When will the tank contain 1.5 kg of salt per liter?
