Heat Transfer Double pipe heat exchangers are used when heat transfer area required is very low when heat transfer area required is very high because it occupies less floor area because it is less costly when heat transfer area required is very low when heat transfer area required is very high because it occupies less floor area because it is less costly 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
