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 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 Giving the surface a mirror finish ANSWER DOWNLOAD EXAMIANS APP

Heat Transfer In a heat exchanger with steam outside the tubes, a liquid gets heated to 45°C, when its flow velocity in the tubes is 2 m/s. If the flow velocity is reduced to 1 m/s, other things remaining the same, the temperature of the exit liquid will be More than 45°C Less than 45°C Equal to 45°C Initially decreases and remains constant thereafter More than 45°C Less than 45°C Equal to 45°C Initially decreases and remains constant thereafter ANSWER DOWNLOAD EXAMIANS APP
