An experiment to determine the convection coefficient associated with airflow over the surface of a thick steel casting involves insertion of thermocouples in the casting at distances of 10 and 20 mm from the surface along a hypothetical line normal to the surface. the steel has a thermal conductivity of 15 w/mk. if the thermocouples measure temperatures of 50 and 40oc in the steel when the air temperature is 100oc, what is the convection coefficient?
