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 Less than 45°C More than 45°C Initially decreases and remains constant thereafter Equal to 45°C Less than 45°C More than 45°C Initially decreases and remains constant thereafter Equal to 45°C ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer For a liquid in laminar flow through a very long tube, when the exit fluid temperature approaches the wall temperature, the equation to be used is Nu = 2Gz0.5 Nu = Gz Nu = 0.023 Re0.8 . Pr0.4 Nu = Gz Nu = 2Gz0.5 Nu = Gz Nu = 0.023 Re0.8 . Pr0.4 Nu = Gz ANSWER DOWNLOAD EXAMIANS APP
