When is heat transfer through a fluid conduction and when is it convection? For what case is the rate of heat transfer higher? How does the convection heat transfer coefficient differ from the thermal conductivity of a fluid?
Water vapor at \(0^{\circ} \mathrm{C}\) and \(1 \mathrm{~atm}\) is flowing over a
flat plate at a velocity of \(10 \mathrm{~m} / \mathrm{s}\). Using appropriate
software, determine the effect of the location along the plate \((x)\) on the
velocity and thermal boundary layer thicknesses. By varying \(x\) for $0
What fluid property is responsible for the development of the velocity boundary layer? For what kinds of fluids will there be no velocity boundary layer on a flat plate?
For what types of fluids and flows is the viscous dissipation term in the energy equation likely to be significant?
An average man has a body surface area of \(1.8 \mathrm{~m}^{2}\) and a skin
temperature of \(33^{\circ} \mathrm{C}\). The convection heat transfer
coefficient for a clothed person walking in still air is expressed as $h=8.6
