From the steam tables, 20 psia is 227.96 degrees

220 deg is 17.186 psia
230 deg is 20.779 psia

Note these are absolute pressures...



Does absolute pressure mean that gage pressure is in addition to atmospheric
pressure? In other words when 5 PSI was indicated on a the pressure vessel
gage then water boiling inside would be about 230F?
