Question

A pure water stream is combined with the concentrated aqueous solution of sulfuric acid to make a dilute stream of sulfuric acid.The incoming flow rate of pure water is10 g/min(liquid at 80°C and 101 kPa; Cp = 4.2 kJ/kg K) . The sulfuric acid streams are also at 80°C; the concentration of the concentrated sulfuric acid stream is 40% and that of the dilute stream is 5%.

(a)Create a process flow diagram for this process ,labeling all streams and energy inputs and outputs.

(b) What is the flow rate of the dilute and concentrated flow of aqueous

sulfuric acid ?

(c) How much energy can be generated using this process?
