206. If the main condenser were operating at a vacuum of 28.5″ Hg, a condensate discharge temperature of 86°F, a sea water inlet temperature of 72°F, and a sea water outlet temperature of 79°F, what would be the condensate depression

Condensate depression is the difference between the saturation temperature at the condenser vacuum and the condensate temperature; this difference is approximately 4F, corresponding to a saturation temperature of 90F and a condensate temperature of 86F.
