Question 1 3 m³/hr of a solution containing 70% (by mass) ethanol and 30% (by mass) water and a quantity of a solution of 55% ethanol-45% water (by mass) are blended to produce a mixture containing 60% by mass ethanol. If the density of the 70% ethanol solution is 862 kg/m³ and the density of the 60% ethanol solution is 891 kg/m³, what mass flowrate of the 55% solution is needed and what is the volumetric flowrate of the product solution? Prepare an input-output table for the process.
Using KVL, calculate the voltages across R1, R2, and R3. Using KCL, calculate currents through R1, R2, and R3. Calculate the power dissipation in each resistor.
Al believes that SUVs have negative social and environmental effects because of their increased carbon monoxide emissions. He proposes eliminating sales taxes on smaller automobiles in favor of higher sales taxes levied on SUVs. Al performs some calculations and comes to the conclusion that based on the current number of SUVs owned in the U.S. exactly the same amount of total sales tax will be collected under his reformed system. Which of the following concepts explains why Al's idea may not work? Answer: Static Forecasting
