Q5. A stirred tank with a volume of 10 L contains pure water. A sugar solution with a concentration of 1 g/L is continuously fed into this tank at a rate of 12 L/h and volume is maintained constant by an overflow (for the excess). (a) Find and equation of X (concentration of sugar in the tank) as a function of time, t. (b) What will be conc. of sugar after 30 minutes. (c) Create a plot for Time (t, min) vs X in Excel Save your Excel worksheet (calculations and your plot) as PDF, and append to your HW. Note that: s dx = 1n|1 x1 = In(1 x)-4 = ln (2) In) In 1-X 1-X
