Computation of the Heat Transfer Coefficient for Given qw

2 Computation of the Heat Transfer Coefficient for Given qw Second Key Problem. 

Given Power generation W, within an object and ambient temperature Required Temperature Tw of the object. 

Assume flow(to be turbulent, which is the case for most practical situations. The laminar cases of Exs. 6.6 and 6.7 are exceptions, provided for illustration. The computation of h requires knowledge of T , which is the question. For an initial estimate of Tw, pick an h from Table 1.2 corresponding to the upper limit of natural convection in the ambient fluid. 

A being the total heat transfer area (2L2 for square plate). 

Follow the five steps of the first key problem to obtain h.
