To clean the impeller blades of a stainless steel tank, planttechnicians pour 210.0 L of a 240.0 g HNO3/L solution in a 820.0-Ltank to soak. When the tank needed to be emptied, the tank wasfirst filled with water entering at a rate of 1.90 L/s. (Figure 1).At t = tF, the tank is completely full of solution. At this pointwater continued to enter the tank at the same rate, but solutionwas also drained from the bottom of the tank at 1.90 L/s (Figure2). Make the assumption that the fluid density does not change andanswer the following questions. 1.) What is the value of tF, thetime it takes to fill the tank? 2.) What is CF, the concentrationof HNO3 in the tank at tF? 3.)At what point after starting to addwater to the tank is the concentration of HNO3 0.0500 of theoriginal concentration?
