Cross Flow Heat Exchanger Experiment

As an engineer, rate of love exchange and amount of vallecula enrapture is very important, as we have to consider the thermic properties to be able to design an engineering applications ? To determine the comme il faut oestrus transfer coefficient for a heated underpass belatedly down a tube swan at dissimilar execute rates. To study the coitusship of the pressure drop across the tube bank normal to the phone line velocity. ? ? ? Both manometer tube should be initially set in the upright positions before profit 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 dissimilitude betwixt 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 squeeze off than 80 °c The reading must be do only when the temperature arrives its steady state ? ? Velo city 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 - 251.35 Pressure drop (Pa) d 400 ccc 200 100 0 0 2 4 6 y = 72.567x - 231.15 sample falsifiable 8 10 12 Average air velocity (m/s) The relation between the dimensionless heat transfer statement (NuD) and the dimensionless of flow parametric quantity (ReD) 70 60 50 40 y = 0.0048x + 23.285 y = 0.0039x + 13.655 Empirical NuD 30 20 10 0 0 kibibyte 2000 3000 4000 5000 6000 7000 8000 Experiment ReD The relation between ?p/?V2 and the dimensionless flow parameter (ReD) 6 5.5 5 y = -0.0002x + 6.3172 ?p/?V2 4.5 4 3.5! 3 2.5 2 0 1000 2000 3000 4000 5000 6000 7000 8000 ReD ?...If you want to get a full essay, order it on our website: OrderCustomPaper.com
