Electric heater wires are installed in a solid wall having a thickness of 8 cm and k = 2.5 w/ the right face is exposed to an environment with h = 50 w/m,°c and t.-30 °c, while the left face is exposed to h = 75 w/m,°c and t. = 50 °c, what is the maximum allowable heat gencration rate such that the maximum temperature in the solid does not exceed 300 °c?

how is this a question? in order for me to answer it i have to understand the question

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.
