20 g (d) TOIq (s) A skell-and-tube exchanger with two tube passes is used to heat ethanol from 60°F to 140°F with steam condensing at 230°F in the shell.27a The BWG 14 steel tubes are in. OD. The design overall coefficient (inside area) is 196 Btu/h- ft- °F, based on an assumed fouling coefficient of 1,000 Btu/h· ft² · °F and a steam film coefficient of 1,800 Btu/h ft. °F. (a) If four tube passes were used, what would be the new overall coefficient? (b) Estimate the new pressure drop if the tube length is unchanged and the calculated Ap for two tube passes was 140 lb,/ft².

-. A skell-and-tube exchanger with two tube passes is used to heat ethanol from 60°F to 140°F with steam condensing at 230°F in the shell.27a The BWG 14 steel tubes are in. OD. The design overall coefficient (inside area) is 196 Btu/h- ft. °F, based on an assumed fouling coefficient of 1,000 Btu/h· ft² · °F and a steam film coefficient of 1,800 Btu/h ft2. °F. (a) If four tube passes were used, what would be the new overall coefficient? (b) Estimate the new pressure drop if the tube length is unchanged and the calculated Ap for two tube passes was 140 lb,/ft.
