Question: A one-effect evaporator operates with a solution whose properties are similar. to pure water. The feed flow is 60000 kg/h, with a concentration of 20%

A one-effect evaporator operates with a solution whose properties are similar. to pure water. The feed flow is 60000 kg/h, with a concentration of 20% (in mass) and temperature of 30 C. Knowing that the concentration at the exit is 40% (in mass) and that the operating pressure of the barometric condenser is 0.075 bar, estimate the consumption of saturated steam in kg/s at 2 bar.
