It turns out that the inlet temperature of the heat exchanger is 36°C, and the outlet temperature is 42°C ； The shell-side steam operating temperature is 55°C, and the operating pressure is 0.16 bar A. The steam flow rate in the shell side is 66 t/h, while the circulating water flow rate in the tube side is 4728 t/h. The heat exchange area of the condenser is 1030 m2. Question: What will be the vacuum level on the shell side of the condenser when the inlet temperature of the circulating water becomes 40.3°C? (All other conditions remain the same; only the inlet temperature of the circulating water increases). Thank you! Appendix C: Condenser parameters and schematic diagram
