Problem 2 (6 pts) SHR 4.1 (3rd edition) Consider the equilibrium stage shown in the figure below. Conduct a degrees-of-freedom analysis by perfor- maing the following steps: 1. List and count the variables. Note that you should include flow rates of each stream as variables. 2. Write and count the equations relating the variables. Just describe the equation (e.g. "energy balance") - you don't need to write the mathematical form down. 3. Calculate the degrees of freedom.
