What is the propane gallon capacity of a properly filled ASME tank at 60°F with a water capacity of 28.6?

To determine the propane gallon capacity of a properly filled ASME tank at 60°F, you can apply the conversion factor that relates the water capacity of the tank in gallons to the propane capacity. The standard factor used is the specific gravity of propane, which is approximately 0.493 when compared to water.

The water capacity of the tank is given as 28.6 gallons. To find the propane capacity, you multiply the water capacity by the specific gravity conversion factor:

1. Calculate the propane capacity in gallons: Propane capacity = Water capacity x Specific gravity of propane Propane capacity = 28.6 gallons x 0.42 (which is the effective conversion factor, accounting for the fact that the tank is typically filled to about 80%).

2. By performing the calculation: Propane capacity = 28.6 x 0.42 = approximately 12.0 gallons.

However, looking at the options provided, it's crucial to recognize that ASME tanks are also usually filled to about 80% of their total water volume to account for expansion and pressure.

The value of 22.9 gallons is based on using a full conversion without considering the restrictive filling practices used (
