Question: Consider a thin 2 4 - cm - long and 2 0 - cm - wide horizontal plate suspended in air at 2 0

Consider a thin

24 -

-

long and

20 -

-

wide horizontal plate suspended in air at

20 \

deg C

.

The plate is equipped with electric resistance heating elements with a rating of

10

.

Now the heater is turned on and the plate temperature rises. Determine the temperature of the plate Ts

,

when steady operating conditions are reached. Neglect the radiation heat transfer.

(

Hint: When you determine the heat transfer coefficients on top and bottom sides, guess that the plate temperature Ts is

40 \

deg C

.

Then determine the actual Ts by an energy balance analysis. You dont need to do iterations in order to eliminate the gap between guessed Ts and actual Ts
