Chapter 1.3, Problem 28E
A steam plain bums two types of coal: anthracite (A) and bituminous (B). For each ton of A bunted, the plant produces 27.6 million Btu of heat, 3100 grams (g) of sulfur dioxide, and 250 g of particulate matter (solid-particle pollutants). For each ton of B burned, the plain produces 30.2 million Btu, 6400 g of sulfur dioxide, and 360 g of particulate matter.
- a. How much heat does the steam plant produce when it burns x1 tons of A and x2 tons of B?
- b. Suppose the output of the steam plant is described by a vector that lists the amounts of heat, sulfur dioxide, and particulate matter. Express this output as a linear combination of two
vectors , assuming that the plant burns x1 tons of A and x2 tons of B. - c. [M] Over a certain time period, the steam plant produced 162 million Btu of heat, 23,610 g of sulfur dioxide, and 1623 g of particulate matter. Determine how many tons of each type of coal the steam plant must have burned. Include a vector equation as part of your solution.

A city of 70000 residents has an average water demand of 250 L/ca.day. The institutional and commercial, and industrial average areas in the city are 250 and 350 Ha, and water demand expected is 20 and 23 m3 /Ha.d. The public water use and water unaccounted for are 10 and 6 % of total municipal water demand, respectively. Calculate total municipal demand and each component quantity as a % of total municipal demand.
Three tanks connected by pipes are shown on a figure below. Originally they contain 10, 20, and
40 gallons of pure water respectively. A brine with salt concentartion of 11b/gal flows into the first
tank with the rate 5 gal/min and a well-mixed solution flows from the first to the second tank with
the rate 8 gal/min. From the second tank the well-mixed solution flows into the third tank with the
rate 8 gal/min and part of a well-mixed solution flows from the third to the first tank with the rate
3 gal/min while another part flows outside the system with the rate 5 gal/min. Write down the sys-
tem of differential equations describing the amount of salt in each tank and put it into the matrix form.

Consider two interconnected tanks as shown in the figure above. Tank 1 initial contains 100L
(liters) of water and 310 g of salt, while tank 2 initially contains 100 L of water and 480 g of
salt. Water containing 15 g/L of salt is poured into tank1 at a rate of 1.5 L/min while the mixture
flowing into tank 2 contains a salt concentration of 30 g/L of salt and is flowing at the rate of
3.5 L/min. The two connecting tubes have a flow rate of 4 L/min from tank 1 to tank 2; and of
2.5 L/min from tank 2 back to tank 1. Tank 2 is drained at the rate of 5 L/min.
You may assume that the solutions in each tank are thoroughly mixed so that the
concentration of the mixture leaving any tank along any of the tubes has the same
concentration of salt as the tank as a whole. (This is not completely realistic, but as in real
physics, we are going to work with the approximate, rather than exact description. The 'real
equations of physics are often too complicated to even write down precisely, much less…

Liquid flows out of tank 1 into 1. tank 2 at 20 gal/hour and back into tank 1 from tank 2 at 5 gal/hour. If the liquid entering tank 1 has 6 lb of sludge per gallon of water and each of the tanks has pure water in them to begin with, find a system of equations that models your system. (Write in matrix form but do NOT solve...)arrow_forwardConsider two interconnected tanks as shown in the figure above. Tank 1 initial contains 100 L (liters) of water and 160 g of salt, while tank 2 initially contains 60 L of water and 345 g of salt. Water containing 15 g/L of salt is poured into tank1 at a rate of 1.5 L/min while the mixture flowing into tank 2 contains a salt concentration of 50 g/L of salt and is flowing at the rate of 4 L/min. The two connecting tubes have a flow rate of 2.5 L/min from tank 1 to tank 2: and of 1 L/min from tank 2 back to tank 1. Tank 2 is drained at the rate of 5.5 L/min. You may assume that the solutions in each tank are thoroughly mixed so that the concentration of the mixture leaving any tank along any of the tubes has the same concentration of salt as the tank as a whole. (This is not completely realistic, but as in real physics, we are going to work with the approximate, rather than exact description. The 'real' equations of physics are often too complicated to even write down precisely, much less…arrow_forward
- Brine containing 2lbs of salt per gallon runs into a tank at 2 gal/min, brine from this tank runs into a second tank at 3 gal/min and brine runs out of the second tank at 3 gal/min. Initially, the first tank conditions 10 gal of brine with 30 lb of salt in solution and the second tank 10 gal of fresh water. Assuming uniform consideration in each tank, find the quantity of salt in the second tank at the end of 5min.arrow_forwardConsider two interconnected tanks of brine solution. Assume that Tank Y contains 20 litres of water and 40 grams of salt, and Tank X contains 20 litres of fresh water. Additionally, fresh water enters Tank Y at a rate of 4 litres/min, and the well-stirred solution flows from Tank Y to Tank X at a rate of 8 litres/ min. Through a different connecting pipe, the well-stirred solution in Tank X drains out at a rate of 8 litres/min, of which some flows back into Tank Y at a rate of 4 litres/min, while the remainder leaves the system.

During manufacturing first, the peanut shell, soil, and sand are removed using a sheller. The removed shell, sand and soil correspond to 2/5 of the raw material by weight entering to sheller. Then the deshelled peanuts, containing 5.6% water, 26% protein, 47.5% fat, 18.6% carbohydrate, and 2.3% ash, are roasted. After roasting the water content decreases to 1.8% due to the evaporation during roasting. The roasted peanuts are then subjected to skin removal operation in a blancher where the skins removed constitute about 1/40 of the roasted peanuts. Finally, clean roasted peanuts are finely ground in a grinder with addition of 1 kg hydrogenated fat and 2 kg honey per 100 kg of roasted deskinned peanuts. The product from the grinder is filled into 250 g jars by using a canning machine. Draw the process and calculate the quantities of all the streams per 100 kg of the roasted product entering blancher.arrow_forward
