Question

Thickness of plate is 10 cm. The temperatures of the two faces of element are 90°c and 60°c. find temperature gradient

Answer 1

Answer:

Explanation:

Thickness of plate is 10 cm. The temperatures of the two faces of element are 90 C and 60C. Find temperature gradient

Answer 2

Given:

The thickness of the plate=10 cm

The temperatures of the two faces of the element= 90°C and 60°C

To find:

The temperature gradient

Solution:

The temperature gradient is 3°C/cm.

We can find the solution by following the given steps-

We know that the temperature gradient of an element depends on the distance between the two surfaces of an element with different temperatures.

The temperature gradient is obtained by dividing the difference in temperatures of surfaces by the distance between surfaces.

The distance between surfaces is equal to the thickness of the plate.

So, the distance=thickness=10cm

The difference in temperatures of the two surfaces of the plate=90°C-60°C=30°C

The temperature gradient= Difference in temperatures/ Distance between surfaces

=30/10

=3°C/cm

Therefore, the temperature gradient is 3°C/cm.
