Specific gravity affects the flow of gas through which components?

Specific gravity is a measure of the density of a gas compared to the density of air. It plays a critical role in how gases flow through systems. When considering components such as orifices and pipes, specific gravity influences the gas flow because it affects how the gas behaves as it moves through these passages.

In orifices, a gas with a higher specific gravity tends to flow differently when compared to a lighter gas. The pressure drop across an orifice can vary depending on the specific gravity, affecting the overall gas flow rate. Similarly, in pipes, specific gravity influences the flow patterns, pressure losses, and velocity of the gas as it travels through.

In contrast, components like valves and regulators, fittings and joints, or controls and sensors may be affected by various factors such as pressure, temperature, and the design of the components themselves, but the direct impact of specific gravity on the flow characteristics of the gas is most prominent in orifices and pipes. Thus, it is essential to consider specific gravity in the context of these components for effective gas flow management and system design.
