Answer:
Explanation:
Given.
Thickness of brass plate
Thermal conductivity of brass
Density of brass
Specific heat of brass
Thermal diffusivity of brass
Temperature of oven
The initial temperature
Plate remain in the oven
Heat conduction in the plate is one-dimensional since the plate is large relative to its thickness and there is thermal symmetry about the center plane.
The thermal properties of the plate are constant.
The heat transfer coefficient is constant and uniform over the entire surface.
The Fourier number is > 0.2 so that the one-term approximate solutions (or the transient temperature charts) are applicable (this assumption will be verified).
The Biot number for this process
The constants and
corresponding to this Biot are, from 11-2 tables.
The interpolation method used to find the
and
The Fourier number
Therefore, the one-term approximate solution (or the transient temperature charts) is applicable.
Then the temperature at the surface of the plates becomes
