Heat Exchanger Design: Calc. Liquid & Vapor Specific Heat

Click For Summary
SUMMARY

The discussion centers on calculating liquid and vapor specific heat for a heat exchanger design involving a process fluid with a flow rate of 1,935,420 lbs/hr at an initial temperature of 168°F, where 38,000 lbs/hr boils and exits at 190°F. The total duty is specified as 45,500,000 BTU/hr. It is concluded that additional temperature measurements are necessary to accurately determine the specific heats, as there is no fixed ratio between them.

PREREQUISITES
  • Understanding of heat exchanger design principles
  • Familiarity with thermodynamic properties of fluids

I have 1,935,420 lbs/hr of process fluid entering all liquid at 168F. 38,000 lbs/hr boils, and the mixture exits at 190F. Total duty is 45,500,000 BTU/hr. Is there a way to calculate the liquid specific heat and the vapor specific heat with this information?

Sorry, no. You need more temperature measurements because there is no set ratio of specific heats.
