A room is well insulated apart from a single-glazed window measuring 1 m2 and 4 mm thick. The internal air temperature is 22oC and outside it is -12oC. If the external convective heat transfer coefficient, hout, is double that of the inside coefficient, and the conductivity in the glass is negligible. Determine hout if Q = 100 W.
