What is the saturation pressure for water at a saturation temperature of 212 degrees F?

The saturation pressure for water at a saturation temperature of 212 degrees Fahrenheit is 14.7 psia. This value is significant because it represents the pressure at which water transitions from liquid to gas (steam) at that specific temperature. At 212 degrees F, which is the boiling point of water at standard atmospheric pressure, the saturation pressure corresponds to atmospheric pressure.

Understanding the concept of saturation pressure is crucial in thermodynamics and in applications involving heating and boiling. At 14.7 psia, the system is in equilibrium; any additional heat will result in the transformation of water into steam, while maintaining that pressure. This relationship is fundamental in processes involving boilers, steam engines, and various other thermal systems used in naval engineering and operations.

For further context, temperatures above or below this value will correspond to different saturation pressures, which is an important aspect to consider when dealing with various thermal systems. This relationship is documented in steam tables and is critical for calculations involving heat transfer and fluid dynamics.
