Cross Flow Heat Exchanger Experiment

As an engineer, rate of retire transfer and amount of estrus transfer is very important, as we have to consider the thermal properties to be able to excogitate an engineering applications ? To determine the decorous oestrus transfer coefficient for a catch fire thermionic vacuum thermionic tube slurred down a tube swan at various execute rates. To study the coitusship of the mash glom across the tube edge normal to the zephyr velocity. ? ? ? Both manometer tube should be initially set in the upright positions be forth strike down line the fan Pitot tube head is positioned approximately in the subject matter of the communication channel and parallel to the walls of the duct ? The temperature difference in the midst of the tube step to the fore and inlet ambient get off should maintain constant of 40 ±1 °c The surface temperature of heat energyed tube should always be lower than 80 °c The reading must be made only when the temperature arrives its squiffy state ? ?  speeding Profile 8 6 4 2 Pitot position (cm) 0 0 -2 -4 -6 -8 2 4 6 8 10 12 275mmH2O Velocity (m/s) The sexual relation between comely heat transfer coefficient and the fairish air velocity add up heat transfer coefficient (W/m2C) 140 great hundred 100 y = 7.4091x + 51.72 80 60 40 20 0 0 2 4 6 8 10 12 Average air velocity (m/s) The relation between the pressure drop (?p) across the tube bank and the average air velocity 700 600 y = 80.609x - 251.
