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) Painting the surface black Roughening the surface Giving the surface a mirror finish Painting the surface white (with aluminium paint) Painting the surface black Roughening the surface ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The advantage of using a 1 - 2 shell and tube heat exchanger over a 1 - 1 shell and tube heat exchanger is Higher tube side heat transfer co-efficient Lower shell side pressure drop Lower tube side pressure drop Higher shell side heat transfer co-efficient Higher tube side heat transfer co-efficient Lower shell side pressure drop Lower tube side pressure drop Higher shell side heat transfer co-efficient ANSWER DOWNLOAD EXAMIANS APP
