Compare the outside coefficient in a crossflow exchanger [Eq. (15.8)] with that predicted by the Donohue equation

Question:

Compare the outside coefficient in a crossflow exchanger [Eq. (15.8)] with that predicted by the Donohue equation [Eq. (15.6)] for typical values of Re and Pr. Why are the values from the Donohue equation so much lower?

Eq. 15.8

Eq. 15.6
