Answer :
Final answer:
The volume of gas that can leak from a limiting orifice in an hour depends on factors like the type of gas, its pressure, and the size of the orifice. A principle known as Graham's Law of Effusion, which states the rate of effusion of a gas is inversely proportional to the square root of mass of its particles, plays a role in this process.
Explanation:
The amount of gas allowed to leak at a leak limiting orifice within an hour depends on several factors including the type and pressure of the gas, and the size of the orifice. However, a principle that governs this process is Graham's Law of Effusion. This law states that the rate of effusion, which can be considered similar to leakage in this context, of a gas is inversely proportional to the square root of the mass of its particles. For instance, lighter gases like hydrogen would leak at a faster rate than heavier gases like oxygen under the same conditions.
Furthermore, the design of containers that hold gases involves allowing a certain degree of leakage to avoid stressing and possibly rupturing the container. Rigid containers such as gas tanks are designed with air gaps to allow them to expand and contract, which also results in some gas leakage.
In essence, the volume of gas that can leak through an orifice in a given period would vary based on the unique parameters of the situation such as the type of gas, gas pressure, and orifice size. It's worth noting that the aim of a limiting orifice is often to control not restrict completely the amount of gas leakage
