Heat Transfer In a shell and tube heat exchanger, There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs The relationship is not generalised The temperature drops in the two fluids and the wall are proportional to individual resistances There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs The relationship is not generalised The temperature drops in the two fluids and the wall are proportional to individual resistances ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer If a single tube pass heat exchanger is converted to two pass, then for the same flow rate, the pressure drop per unit length in tube side will Remain unchanged Increase by 1.8 times Decrease by 22 Increase by 216 Remain unchanged Increase by 1.8 times Decrease by 22 Increase by 216 ANSWER DOWNLOAD EXAMIANS APP

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 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 Giving the surface a mirror finish ANSWER DOWNLOAD EXAMIANS APP
