3 Condensate at steam temperature andunder 100 psig pressure has a heatcontent of 308.8 Btu per pound. (SeeColumn 4 in Steam Table.) If this conden-sate is discharged to atmosphericpressure (0 psig), its heat content instantlydrops to 180 Btu per pound.ote the extra heat and higher temperature required tomake water boil at 100 pounds pressure than at atmospheric pressure. Note, too, the lesseramount of heat required to change water to steam at the higher temperature.
