Flux is always defined based on: A surface. A vector field (e.g. the electric field). and can be thought of as a measure of the number of field lines from the vector field that cross the given surface. For that reason, one usually refers to the “flux of the ...

NettetThe outer surface of a 0.2m-thick concrete wall is kept at a temperature of –5°C, while the inner surface is kept at 20°C. The thermal conductivity of the concrete is 1.2 W/(m K). Determine the heat loss through a wall 10 m long and 3 m high. GIVEN 10 m long, 3 m high, and 0.2 m thick concrete wall NettetThis procedure can be easily done because of capillary action, the ability of a liquid to flow up a small tube against gravity, as shown in Figure 7.1.7. When your finger is pricked, a drop of blood forms and holds together due to surface tension—the unbalanced intermolecular attractions at the surface of the drop.
