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 black Painting the surface white (with aluminium paint) Roughening the surface Giving the surface a mirror finish Painting the surface black Painting the surface white (with aluminium paint) Roughening the surface ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer A hollow sphere and a solid sphere of the same material and equal radii are heated to the same temperature. In this case, The cooling rate will be the same for the two spheres and hence the two spheres will have equal temperatures at any instant Both B & C Both will absorb equal amount of radiation from the surrounding in the beginning Both the spheres will emit equal amount of radiation per unit time in the beginning The cooling rate will be the same for the two spheres and hence the two spheres will have equal temperatures at any instant Both B & C Both will absorb equal amount of radiation from the surrounding in the beginning Both the spheres will emit equal amount of radiation per unit time in the beginning ANSWER DOWNLOAD EXAMIANS APP
