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 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 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Pick out the correct equation. JH = (St)(Pr)1/3 = f/2 JH = (St)1/3(Pr) = f/2 JH = (St)(Pr)2/3 = f/2 JH = (St)2/3(Pr) = f/2 JH = (St)(Pr)1/3 = f/2 JH = (St)1/3(Pr) = f/2 JH = (St)(Pr)2/3 = f/2 JH = (St)2/3(Pr) = f/2 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In a shell and tube heat exchanger, There is no relationship between temperature drop and resistance The temperature drops in the two fluids and the wall are proportional to individual resistances The relationship is not generalised The temperature drop is inversely proportional to the resistance across which the drop occurs There is no relationship between temperature drop and resistance The temperature drops in the two fluids and the wall are proportional to individual resistances The relationship is not generalised The temperature drop is inversely proportional to the resistance across which the drop occurs ANSWER DOWNLOAD EXAMIANS APP
