4 Computation of the Heat Transfer Coefficient for External Flow 

Given Free-stream velocity and temperature Too, and temperature Tw of the object. Required Heat loss qw from or energy generation u within the object. 

From Table B.2 for gases or Table B.3 for liquids in the Appendix, read the following three properties for ambient fluid at the film temperature Tj  

Do not use any interpolation pick available numerical values closest to Tf. 

Using Voo, v, and a characteristic length D, compute the Reynolds number
