Q1: 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.A Condensation
B Grashoff
C Stantan
D Brinkman
ANS:D - Brinkman The 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 Brinkman number (Br). The Brinkman number is defined as the ratio of viscous heating to conductive heat transfer and is given by: Br=viscous heatingconductive heat transferBr=conductive heat transferviscous heating Therefore, the correct option is: Brinkman |
