Question:
Calculate the heat transfer coefficient for film boiling of water on a 1.3 cm horizontal tube if the tube temperature is 550?C and the system is placed under pressure of 1/2 atm.GIVENFilm boiling of water on a horizontal tubeTube outside diameter (D) = 1.3 cm = 0.013 mTube temperature (Tt) = 550?CPressure = 1/2 atm = 50,660 N/m2ASSUMPTIONSSteady stateTube temperature is uniform and constantThe viscosity, specific heat, and thermal conductivity of the vapor can be approximated by those of steam at 1 atm pressureRadiation across the vapor film isnegligible
