Question
1- The following observations were recorded during a test on a steam condenser of counter
flow:
Barometer reading = 765 mmHg
Vacuum reading = 710 mmHg
Steam and air temperature = 35 •C
Condensate temperature = 28 •C
Condensate collected per hour = 2 tons
Cooling water collected per hour = 60 tons
Inlet cooling water temperature = 10 •C
Exit cooling water temperature = 25 •C
Cooling water tubes specification = Thin tubes D=2 cm ,L=5 m ,n=350,
Determine:
a- The vacuum efficiency.
b- The condenser efficiency.
c- Quality of steam x entering the condenser.
