Find the average freeconvection heat transfer coefficient of

Find the average free-convection heat transfer coefficient of a bedroom wall (assume 3m-high vertical walls) of a home during winter and summer conditions. -Winter conditions: 23°C interior air and 7°C wall surface temperature -Summer conditions: 29°C interior air and 40°C wall surface temperature

During Winter condtitions

h = 1.42 * (T_interior - T_wall / H )^0.25

h = 1.42 * ((23 - 7) / 3)^0.25

h = 2.158 W/m^2K

During Summer condtitions

h = 1.42 * (T_interior - T_wall / H )^0.25

h = 1.42 * (-(29 - 40) / 3)^0.25

h = 1.965 W/m^2K
