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 Initially decreases and remains constant thereafter More than 45°C Equal to 45°C Less than 45°C Initially decreases and remains constant thereafter More than 45°C Equal to 45°C Less than 45°C ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Log mean temperature difference (LMTD) cannot be used, if heat transfer co-efficient over the entire heat exchanger is not constant the heat capacity is not constant and there is a phase change. there exists an unsteady state none of the listed here heat transfer co-efficient over the entire heat exchanger is not constant the heat capacity is not constant and there is a phase change. there exists an unsteady state none of the listed here ANSWER DOWNLOAD EXAMIANS APP
