Awall has inner and outer surface temperatures of 22 and 10°c, respectively. the interior and exterior air temperatures are 26 and 10°c, respectively. the inner and outer convection heat transfer coefficients are 5 and 20 w/m².k, respectively. calculate the heat flux from the interior air to the wall, from the wall to the exterior air, and from the wall to the interior air. is the wall under steady-state conditions?
