What is the latent heat of vaporization at boiling point in BTU per gallon?

The latent heat of vaporization at the boiling point for liquid propane is often cited as approximately 773 BTU per gallon. This value refers to the amount of energy required to convert one gallon of liquid propane into vapor without changing its temperature.

Understanding latent heat is crucial in the context of LP gas systems and appliances, as it directly impacts the efficiency and performance of these systems. The higher the latent heat, the more energy is required to vaporize the liquid, which affects the overall efficiency of gas appliances, including stoves and heating systems using propane.

In practical applications, knowing this value helps in properly sizing equipment and ensuring safe and efficient operation. Calculating the energy needs during vaporization ensures that systems are designed to handle the thermal demands placed on them during operation, contributing to both safety and efficiency.
