Convection Correlations and Internal flow (circular tube) – Heated air required for a food- drying process is generated by passing ambient air at 20 °C through long, circular tubes (D = 50 mm, L = 5 m) housed in a steam condenser. Saturated steam at atmospheric pressure condenses on the outer surface of the tubes, maintaining a uniform surface temperature of 100°C. If an air flow rate of 0.01 kg/s is maintained in each tube, determine the air outlet temperature Tm.o and the total heat rate for a tube. Assume average Tm = 325 K.

Question
Transcribed Image Text:Convection Correlations and Internal flow (circular tube) – Heated air required for a food-
drying process is generated by passing ambient air at 20 °C through long, circular tubes (D = 50 mm, L = 5
m) housed in a steam condenser. Saturated steam at atmospheric pressure condenses on the outer surface of
the tubes, maintaining a uniform surface temperature of 100°C. If an air flow rate of 0.01 kg/s is maintained
in each tube, determine the air outlet temperature Tm.o and the total heat rate for a tube. Assume average Tm
= 325 K.
