Heat transfer rate and heat transfer area
Thread Content
This post was last edited by penryn on 2011-7-1 09:59. There is a project involving wastewater and clean water; the clean water flows in the shell side while the wastewater flows in the tube side. The heat transfer rate is 1400 kW, with the wastewater inlet temperature at 25°C and the outlet temperature at 30°C; the clean water inlet temperature is 32°C and the outlet temperature is 27°C. The design pressure is 0.6. I would appreciate it if experts could use their experience to advise on what value should be used for the heat transfer area. Is 80 square meters a suitable value? What other information is needed? The temperature difference is 5 degrees Celsius.
What about the specific temperature and pressure? Just a temperature difference isn’t enough. The difference between 100 and 95 is very different from the difference between 10 and 5
Agree with the suggestion from the first floor; the data is incomplete, and the heat exchange temperature is very important.
Wastewater inlet temperature: 25°C, outlet temperature: 30°C; clean water inlet temperature: 32°C, outlet temperature: 27°C. Design pressure: 0.6. Seeking advice.

Why isn’t anyone answering? I’m anxious. Experts
