In a heat exchanger, as shown in accompanying figure, air flows over brass tubes of 1.8- cm-ID and 2.1-cm-OD that contain steam. The convection heat-transfer coefficients on the air and steam sides of the tubes are 70 W/(m2 K) and 210 W/(m2 K), respectively. Calculate the overall heat transfer coefficient for the heat exchanger (a) based on the inner tube area, (b) based on the outer tube area but assume that a fouling factor of 0.00018 (m2 K)/W has developed on the inside of the tube during operation.
GIVEN
• Air flow over brass tube containing steam
• Tube diameters Inside (Di) = 1.8 cm = 0.018 m
Outside (Do) = 2.1 cm = 0.021 m
• Convective heat transfer coefficients Air side h o= 70 W/(m2 K)
Steam side h i= 210 W/(m2 K)
• Fouling factor on the inside of the tube (Rd) = 0.0018 (m2 K)/W
FIND
• The overall heat transfer coefficient for the heat exchanger based on
(a) the inner tube area (Ui) and (b) the outer tube area (Uo)
ASSUMPTIONS
• The heat transfer coefficients are uniform over the transfer surfaces
