What is the typical resistance per foot of 3/16 in beer lines?

The typical resistance per foot of 3/16 inch beer lines is indeed 2.0 psi. The resistance in beer lines is a crucial factor that affects the flow rate of beer from a keg to a tap. The diameter of the line plays a significant role in determining this resistance, with narrower lines generally having higher resistance.

For 3/16 inch diameter lines, the established standard resistance is approximately 2.0 psi per foot. This value is important for calculating the correct line length and determining appropriate pressure settings to ensure the beer pours correctly without issues such as excessive foaming or flatness.

Understanding this resistance allows draft technicians and brewers to properly design and maintain draft systems, ensuring optimal performance and consistent quality of the beer being served.
