Propane gas enters a continuous adiabatic heat exchanger' at 40°C and 250 kPa and exits at 240°C superheated steam at 300°C and 5.0 bar enters the exchanger flowing counter currently to the propane and exits as a saturated liquid at the same pressure.(a) Taking as a basis 100 mol of propane fed to the exchanger, draw and label a process flowchart. Include in your labeling the volume of propane fed (m3), the mass of steam fed (kg), and the volume of steam fed (m3).
