Question details

Problem 3.064 The air inside a chamber at T í = 50 C is heated con vectively with hi = 20 w m2 K by a 100 m thick wall having a thermal conductivity of 4 W/ K and a uniform heat generation of 2000 w/m3 To prevent any heat generated within the wall from being lost to the outside of the chamber at T25 C with ho5 W/m2-K, a very thin electrical strip heater is placed on the outer wall to provide a uniform heat flux, go Strip heater, go Wall, k, q Outside chamber Inside chamber Physical Properties Mathematical Functions Step 1 Your answer is incorrect. Try again 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 W/m2 275 W/m2 exact number, no tolerance▼ Step 2 For the case where none of the heat generated in the wall is lost to the outside chamber, determine the temperature at the interface between the strip heater and the wall, in °C T1 the tolerance is +/-2% By accessing this Question Assistance, you l learn while you earn points based on the Point Potential Policy set by your instructor.
