Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Flows through the tube Can flow either inside or outside the tubes Flows outside the tubes Should not be used as it gives very high pressure drop Flows through the tube Can flow either inside or outside the tubes Flows outside the tubes Should not be used as it gives very high pressure drop 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 Equal to 45°C Initially decreases and remains constant thereafter Less than 45°C More than 45°C Equal to 45°C Initially decreases and remains constant thereafter Less than 45°C ANSWER DOWNLOAD EXAMIANS APP
