Question
Saturated vapour of benzene at 1 atm pressure enters a horizontal 16 BWG 3/4 inch tube (o.d. 19 mm, i.d. = 16 mm) at a mass velocity of 20 kg/m² s. A coolant flows outside the tube, and the wall temperature is maintained at 55°C. What fraction of the vapour will condense if the tube is 0.5 m long? The following data for benzene are available at the mean film temperature, i.e. (80+55)/2= 67.5°C: p = 815 kg/m³, ,0.381 CP, Cpl 1.94 kJ/kg °C, k=0.13 W/m °C, L,= 391 kJ/kg. Normal boiling point of benzene is 80°C (353 K); for saturated benzene vapour at 1 atm pressure, p, = 2.7 kg/m³, H4, 89 μP). = =
