Two streams flow into a mixing unit. Stream 1 is 35wt% species-A and the balance species- B. Stream 2 is pure species-C. Stream one flows at 10 kg/min. Stream 3 is the well-mixed output stream from the mixer. Draw and label the process flow diagram for this system labeling each known and unknown variable. Evaluate the three scenarios below. For each scenario list the known and unknown quantities, then clearly show the procedure for solving for the unknown quantities. Explain your reasoning for each step. (a) If stream 2 flows at 5 kg/min, calculate the mass flow rate and composition of stream 3. (b) If stream 3 flows at 20 kg/min, calculate the mass flow rate of stream 2 and the composition of stream 3. (c) If the desired mass fraction of species-A in stream 3 is 0.20, what is the required mass flow rate of stream 2 and the mass flow rate of stream 3?
