Look at Figure 2, which shows the pressure-enthalpy diagram for water. As you can see, at a pressure of 15 psig (29.7 psia), water begins to boil at 253°F. At that pressure/temperature condition, the addition of 1,165 Btu of heat energy is required to change each pound of water to steam. At 0 psig (14.7 psia), water begins to boil at 212°F.

the water temperature vs. the enthalpy of the water (heat con-tent in Btu/lb). We all know that water boils at 212ºF (atmos-pheric pressure at sea level). By definition, water at atmospher-ic pressure, at a temperature lower than 212ºF, is subcooled. So, we start with subcooled water at 42ºF, and begin transfer-ring heat to it.
