The heat transfer coefficient on the inside of a copper tube (1.9 cm ID and 2.3 cm OD) is 500 W/(m2 K) and 120 W/(m2 K) on the outside, but a deposit with a fouling factor of 0.009 (m2 K)/W (based on the tube outside diameter) has built up over time. Estimate the percent increase in the overall heat transfer coefficient if the deposit were removed.GIVENHeat transfer through a copper tubeHeat transfer coefficientsInside (hi) = 500 W/(m2 K)Outside (ho) = 120 W/(m2 K)Tube diametersInside (Di) = 1.9 cm = 0.019 mOutside (Do) = 2.3 cm = 0.023 mFouling factor (Rd) = 0.009 (m2 K)/WASSUMPTIONSConstant thermal conductivity propertiesThe copper ispure
