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 Less than 45°C Equal to 45°C More than 45°C Initially decreases and remains constant thereafter Less than 45°C Equal to 45°C More than 45°C ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The left face of a one dimensional slab of thickness 0.2 m is maintained at 80°C and the right face is exposed to air at 30°C. The thermal conductivity of the slab is 1.2 W/m.K and the heat transfer co-efficient from the right face is 10 W/m².K. At steady state, the temperature of the right face in °C is 48.7 63.8 71.2 77.2 48.7 63.8 71.2 77.2 ANSWER DOWNLOAD EXAMIANS APP
