Consider a blending tank that has the same dimensions and nominal flow rates as the storage tank in Exercise 2.13 but that incorporates a valve on the outflow line that is used to establish flow rate w3. (For this exercise, there is no leak in the tank as in Exercise 2.13.) In addition, the nominal inlet stream mass fractions of component A are x1 = x2 = 0.5. The process has been operating for a long time with constant flow rates and inlet concentrations. Under these conditions, it has come to steady state with exit mass fraction x = 0.5 and level h = 1.75 m. Using the information below, answer the following questions: (a) What is the value of w3? The constant, Cv?
