Heat Transfer The heat transfer by radiation from a mild steel surface is to be reduced by reducing the emissivity of the surface. This can be best achieved by Roughening the surface Painting the surface black Painting the surface white (with aluminium paint) Giving the surface a mirror finish Roughening the surface Painting the surface black Painting the surface white (with aluminium paint) Giving the surface a mirror finish ANSWER DOWNLOAD EXAMIANS APP
