Superheated steam at 10bars pressure and 210oc flows at 2kg/s into a heat exchanger.

Superheated steam at 10bars pressure and 210oc flows at 2kg/s into a heat exchanger. the steam preheats a reactor feed by transfering 450kw of heat. the pressure drop across the heat exchanger is negligible.
a. draw the flowchart for this process
b. lable all the process strams and unite operations.
c. calculate the enthalpy, temperature, phase and the quality of the resulting stream.
