The air inside a chamber at $T_{,i}=50C$ is heated convectively with $h_i=20\frac{W}{m^2}*K$ by a $300-mm-$thick wall having a thermal Step $3$

For the case where none of the heat generated in the wall is lost to the outside chamber, determine the wall surface temperature

at the inside chamber, in $C.$

conductivity of $4\frac{W}{m}*K$ and a uniform heat generation of $2000\frac{W}{m^3}.$ To prevent any heat generated within the wall from being lost

to the outside of the chamber at $T_{,o}=25C$ with $h_o=5\frac{W}{m^2}*K,$ a very thin electrical strip heater is placed on the outer wall to

provide a uniform heat flux, $q_o^{\text{'}\text{'}}.$

Step $1$

X Your answer is incorrect.

For the case where none of the heat generated in the wall is lost to the outside chamber, determine the heat transfer rate per unit

area at the interface between the strip heater and the wall, in $\frac{W}{m^2}.$
