A measure of the extent to which viscous heating is important relative to the heat flow resulting from the impressed temperature difference is represented by the _______________ number?
Correct answer: B. Brinkman
- A. Condensation
- B. Brinkman
- C. Stanton
- D. Grashoff
Explanation
The Brinkman number compares heat generated by viscous dissipation with heat conducted because of the imposed temperature difference. Grashof concerns natural convection, while Stanton concerns convective heat transfer relative to fluid heat-capacity flow.
