Final answer:
The maximum gross capacity of pressure tanks varies based on design, use, and construction material. A typical scuba tank can hold about 50 liters, while other tanks, such as those for gasoline, may hold around 60 liters, taking into account the thermal expansion properties of materials.
Step-by-step explanation:
The maximum gross capacity of pressure tanks does not have a standard or fixed value as it can vary greatly depending on the design, purpose, and construction of the tank. For instance, a typical scuba tank might hold about 50 liters (13 gallons) of air, while a pressure tank for gasoline could hold approximately 60.0 liters.
When discussing the maximum gross capacity in the context of a gas tank for gasoline, it is noteworthy that a gas tank with a volume of 60 liters can significantly expand due to the thermal properties of gasoline and steel, impacting the volume and pressure that the tank can withstand safely.
Factors such as the material of the tank, the pressure rating, and the intended use (storage of air for diving, fuel storage, etc.) play critical roles in determining the total capacity of a pressure tank. For example, a large scuba tank with a volume of 18 liters is rated for a pressure of 220 bar, which shows the relationship between the volume and pressure capacities of such tanks.
The calculations concerning the pressure exerted, the mass of the gas, temperature, and volume are intrinsic to understanding the capacity of pressure tanks in real-world applications, as illustrated in various examples involving gas laws and thermal expansion.
