3. Saturated steam at 55°C is to be condensed at a rate of 10 kg/h on the outside of a 3.8-cm-outer-diameter horizontal tube whose surface is maintained at 45°C by the cooling water. Assume wavy laminar flow and that the tube diameter is large, relative to the thickness of the liquid film at the bottom of the tube. Given: The properties of water at the saturation temperature of 55°C are: hfg = 2371 × 103 J/kg Pv=0.1045 kg/m³ The properties of liquid water at the film temperature of Tr-(Tsat + T)/2 = 50°C P=988.1 kg/m³ H=0.547 x103 kg/m.s Vi Hil P=0.554 × 10-6 m²/s Cpl 4181 J/kg.
