Question:
Reconciliation of inaccurate process measurements is an important problem in process control that can be solved using optimization techniques. The flow rates of streams B and C have been measured three times during the current shift (shown in Fig. E). Some errors in the measurement devices exist. Assuming steady-state operation (WA = constant), find the optimal value of WA (flow rate in kg/h) that minimizes the sum of the squares of the errors for the material balance, WA + wCWB.
