Use HYSYS to solve a simple energy balance.
Mixing a cold water stream (120 kg/min 30C) and a hot water stream (175 kg/min 65 C) then heating the streams to saturated vapor at 17 Bar. What is the duty?
The basic simulation flow sheet will appear as this
Now we will simulate the above flow sheet and obtain the result
The Heat duty reuqired is
Additional results of each stream is follows
