I'm new in learning HTRI. I'm having some problem with my calculation.

 

Shell side fluid is NG. The inlet temperature is -20^oC, outlet is higher than 3^oC.

 

Tube side fluid is seawater. The inlet temperature is 10^oC, outlet is higher than 9.3^oC. The material used for tube side is titanium.

 

When I run the program, the HTRI warning message that "The maximum process temperature is outside the correlational range of the thermal conductivity correlation. The thermal conductivity was calculated at the temperature limit. For tube metal number  323 this temperature limit is 70F". I'm not sure about the problem.

 

Could you please help me to show this problem? Thank you for your help. Sorry because of my bad English.

Try to change manually metal thermal conductivity.
