A10 m^2 plane-wall with a thickness of 1m dissipates heat to ambient air through its two surfaces on the left and right, respectively. the thermal conductivity of the wall is = 20 w/m*k . the convection heat transfer coefficient at its external surface ℎ = 20 w/(m^2)k . the measured surface temperature is 50 °c. the ambient air temperature is 0 ℃. (1) draw a schematic figure of this wall and have all parameters known clearly presented; (2) find the heat dissipated from this wall to ambient air; (3) find the maximum temperature within this wall;

2)20Kw

3)75C

Explanation:

Hello, to solve this problem we must use the equations that describe the heat transfer by convection and conduction.

for point B

We use the convection heat transfer equation on one side of the wall and multiply it by 2 since they are two exposed surfaces.

for point C we use heat transfer by conduction to the middle of the wall with L = 0.5m.

answer:

design model: consists of design geometry; can be 2d or 3d; typically has a black background.

design files: drawing created with microsoft expression design, a drawing and design program for windows; may contain both vector and raster graphics; can also include multiple layers and various image effects.

elements: an element is a single part of a larger group.
