Question: What is a good estimate for condensing side heat transfer coefficients inside tubes?
Keywords: shell,tube,heat,transfer,exchangers,condensing,coefficients,estimate,
Answer: The following is a close estimate of the maximum heat transfer rate for total condensation. It is based on the maximum for the average hydrocarbon is 750 BTU/hr-ft2-F. It is good for other types of chemical compounds. Hi = 750 (Kliq / 0.07) (0.9) Where Kliq is the liquid thermal conductivity of the condensate For example this gives a maximum heat transfer rate for steam to be 3600.Source: Gulley Computer Associates
