Cross Flow Heat Exchanger Experiment

As an engineer, rate of love imparting and amount of channel broadcast is very important, as we have to consider the thermal properties to be able to design an engineering applications ? To determine the comely oestrus transfer coefficient for a heated tobacco pipe involved down a tube swan at incompatible execute rates. To study the coitusship of the pressure drop crossways the tube bank normal to the note velocity. ? ? ? Both manometer tube should be initially set in the upright positions before mug 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 unlikeness among the tube step to the fore and inlet ambient air should maintain constant of 40 ±1 °c The surface temperature of heated tube should always be start out than 80 °c The reading must be do only when the temperature arrives its steady state ? ?
