Question
Saturated dry steam at 1500 kPa passes through a 100 mm steel pipe (t = 5 mm), with a total length of 100 m. the steam line is insulated with a 50 mm thickness of 85% magnesia which has a thermal conductivity of 0.25 W/m degrees C. For a mass flow rate of 600 kg steam per hour and an ambient air temperature of -10 degrees C, determine the quality of steam after passing through this pipe.
Surface film conductance of condensing steam, h = 5500 W/m2 - degrees C
Surface film conductance of air, h = 12 W/m2 - degrees C
Thermal conductivity of pipe material, k = 153 W/m degrees C
Properties of steam, 1500 kPa(tsat= 198.32 degrees C)
hg = 2792.2 kJ/kg
hf = 844.89 kJ/kg
hfg = 1947.3 kJ/kg
