Heat Transfer The average heat transfer co-efficient over the entire length of the plate (ha) and the local heat transfer co-efficient (hL), in case of heat transfer over a flat plate in lminar zone is related as Ha = hL Ha = 2hL Ha = 0.8hL Ha= 5hL Ha = hL Ha = 2hL Ha = 0.8hL Ha= 5hL 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 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
