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 Giving the surface a mirror finish Painting the surface white (with aluminium paint) Roughening the surface Painting the surface black Giving the surface a mirror finish Painting the surface white (with aluminium paint) Roughening the surface Painting the surface black ANSWER DOWNLOAD EXAMIANS APP
