Question: A multiple effect evaporator system consists of three evaporator units in series. The feed solution enters the first evaporator with a flow rate of 10,000 kg/hr and a concentration of 5% solute. Each evaporator operates at a vacuum pressure of 60 kPa. The steam used in the first effect has a temperature of 130C and a pressure of 300 kPa. The steam is condensed and recycled to subsequent effects. The overall heat transfer coefficient for each effect is 800 W/m.K. Calculate the final concentration of the solute in the product stream exiting the third evaporator. Assume steady-state operation and neglect any losses or heat gains. Question: A multiple effect evaporator system consists of three evaporator units in series.
