Air at 16?C and atmospheric pressure enters a 1.25-cm-ID tube at 30 m/s. For an average wall temperature of 100?C, determine the discharge temperature of the air and the pressure drop if the pipe is (a) 10 cm long and (b) 102 cm long.GIVENAtmospheric air flowing through a tubeEntering air temperature (Tb,in) = 16?CTube inside diameter (D) = 1.25 cm = 0.0125 mAir velocity (V) = 30 m/sAverage wall surface temperature (Ts) = 100?CASSUMPTIONSSteady stateThe tube issmooth
