The inside surface of a 1 m long vertical 5 cm-ID tube is maintained at 120?C. For saturated steam at 350 kPa condensing inside, estimate the average heat transfer coefficient and the condensation rate, assuming the steam velocity is small.GIVENSteam condensing inside a vertical tubeTube length (L) = 1 mTube inside diameter (D) = 5 cm = 0.05 mTube surface temperature (Ts) = 120?CSteam pressure (p) = 350 kPaASSUMPTIONSSteady stateThe steam velocity is smallFilm condensationoccurs
