1. The problem statement, all variables and given/known data Consider a brick wall, 4.0 m high, 6.0 m wide and 300 mm thick, where the thermal conductivity of the brick is 0.8 W.m-1.K-1. During a particular one-hour period, the temperatures of the inner and outer surfaces were measured to be T1 14oC and T2 6oC respectively. The average rate of heat transfer Q*=Rate of heat tranfer (i think) 2. Relevant equations The equation that I am trying to use is Q* = (T1-T2)*(k)*(A)/^X not sure if correct. 3. The attempt at a solution ^X is just the thickness of material A is 4*6=24m^2 k = 0.8W/mK so i filled in and the divided by 3600s to get an answer in joules, i know i have can wrong can someone help me out with what formulae to use for this question?
