Question
Water at an average temperature of 107°C and an average velocity of 3.5 m/s flows
through a 5m long stainless steel tube (k = 14.2 W/m·°C) in a boiler. The inner and outer
diameters of the tube are Di =1.0 cm and Do=1.4 cm, respectively, and the fouling factor
Rf,i = 0.0005 m2·°C/W on the inner surface of the tube. If the convection heat transfer
coefficient at the outer surface of the tube where boiling is taking place is ho=8400
W/m2·°C. Determine the overall heat transfer coefficient Ui of this boiler based on the
inner surface area of the tub
