Heat and Mass Transfer

Please answer legibly. Heat and Mass Transfer The feed rate to a

The feed rate to a single effect evaporator is 20000lb/h of a 30%NaOH solution at 90F. This solution is concentrated to 60%NaOH solution using steam at 20.7lbf/in2 gauge pressure. The vapor space of the evaporator has the absolute pressure of 2.5lbf/in2. Calculate the amount of liquid concentrate produced, vapor produced, boiling point of the solution, enthalpy of liquid concentrate, latent heat of steam, enthalpy of vapor, amount of steam and surface area required when overall heat transfer coefficient is 200BTU/ft2hF.
