What is the heating value of propane?

The heating value of propane is approximately 2500 BTU per cubic foot. This value reflects the amount of energy that can be obtained from propane when it is burned, which is significantly higher than many other energy sources. Understanding the heating value is essential for applications involving heating, cooking, and powering equipment, as it directly affects how much propane is needed to achieve a certain level of energy output.

In the context of the other options, there are substantial differences in their values compared to the accepted heating value of propane. The lower options do not represent the energy density of propane accurately, which is crucial for efficient system design and operation. Conversely, the much higher value of 3250 BTU/cf exceeds what is generally accepted for propane, indicating that such a figure would be inappropriate for practical applications involving this fuel. Thus, the heating value of propane is accurately represented by the value of 2500 BTU/cf.
