Question
2- The following data relate to a two-pass surface condenser:
Steam condensed = 1540 kg/hr
Temperature of cooling water when it enters the condenser = 15° C
Temperature of cooling water when it leaves the condenser = 30 ° C
Vacuum in the condenser = 675 mm of Hg
Barometer reading = 750 mm of Hg
Temperature of condensate = 32 ° C
Quality of exhaust steam = 0.92
Water velocity in tubes = 2.6 m/s
Outside diameter of tubes = 2.8 cm
Thickness of tubes = 0.03 cm
Heat Transfer coefficient = 3.35 kJ/h/cm
Determine
Area of the tube surface required
а-
b- No. of tubes
c- Length of tubes
