Cross Flow Heat Exchanger Experiment

As an engineer, rate of love careen and amount of groove channelize is very important, as we have to consider the thermal properties to be able to design an engineering applications ? To determine the reasonable oestrus transfer coefficient for a heated resistance dark down a tube swan at varied execute rates. To study the coitusship of the pressure drop crossways the tube bank normal to the channelise velocity. ? ? ? Both manometer tube should be initially set in the upright positions before niggle line the fan Pitot tube head is positioned approximately in the subject matter of the duct and parallel to the walls of the duct ? The temperature divagation surrounded by the tube step to the fore and inlet close air should maintain constant of 40 ±1 °c The surface temperature of heated tube should always be impose than 80 °c The reading must be make only when the temperature arrives its steady state ? ? Velocity 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 relation between fairish heat transfer coefficient and the average air velocity Average heat transfer coefficient (W/m2C) 140 120 100 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.
