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.

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.

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

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_forwardA tank contains 175 liters of fluid in which 20 grams of salt is dissolved.
