What is the vapor pressure of propane at 70°F?

The vapor pressure of propane at 70°F is indeed approximately 127 PSI, which is important to understand for various applications, particularly in the storage and handling of the gas. Propane, being a liquefied petroleum gas, significantly increases in pressure as the temperature rises, and its vapor pressure at different temperatures is a critical factor in system design and safety considerations.

Understanding vapor pressure helps technicians ensure that the pressure relief devices and storage vessels are adequate to handle the pressure exerted by the propane under varying temperatures. For instance, at 70°F, the vapor pressure indicates that the liquid propane will exert a substantial amount of pressure in a closed system, which needs to be managed properly to prevent overpressure situations that could lead to leaks or ruptures.

Recognizing the correct vapor pressure is essential for safely operating propane systems, and the value of 127 PSI aligns well with established engineering references and propane property tables. This knowledge is invaluable for anyone working with propane to ensure they can apply proper safety protocols and maintain system integrity.
