Saturated steam at 0.1 bar condenses with a convection coefficient of 6800 W/(m²-K) on the outside of a brass tube having inner and outer diameters of 16.5 and 19 mm, respectively. The convection coefficient for water flowing inside the tube is 5200 W/(m2-K). Estimate the steam condensation rate per unit length of the tube when the mean water temperature is 30 °C. The specific latent heat is 2390 kJ/kg, and the thermal conductivity of the brass tube is 110 W/(m-K). The saturation temperature of steam at 0.1 bar is 47 °C. The specific heat capacity is 4179 J/(kg-K). The answer should be given using the unit of g/s. Hint: Specific latent heat should be corrected with the inclusion of thermal advection effects.

Transcribed Image Text:Saturated steam at O0.1 bar condenses with a convection coefficient of 6800 W/(m²-K) on the
outside of a brass tube having inner and outer diameters of 16.5 and 19 mm, respectively. The
convection coefficient for water flowing inside the tube is 5200 W/(m²-K). Estimate the steam
condensation rate per unit length of the tube when the mean water temperature is 30 °C. The
specific latent heat is 2390 kJ/kg, and the thermal conductivity of the brass tube is 110 W/(m-K).
The saturation temperature of steam at 0.1 bar is 47 °C. The specific heat capacity is 4179 J/(kg-K).
The answer should be given using the unit of g/s. Hint: Specific latent heat should be corrected with
the inclusion of thermal advection effects.
