How many feet of 3/16 tubing are typically used to serve beer at 10-15 psi?

The typical length of 3/16-inch tubing used to serve beer at pressures of 10-15 psi is essential for maintaining proper flow rates and carbonation levels. In this pressure range, a length of 5-7 feet allows for adequate resistance to ensure the beer is dispensed properly without excessive foaming or under-carbonation.

The tubing functions by creating resistance against the flow of beer, which helps balance the pressure and carbonation levels effectively. Too short a length may result in beer pouring too quickly, leading to excessive foam, while too long a length can cause the beer to dispense too slowly or become under-carbonated. Thus, the 5-7 feet range is optimal for the specified pressure, making it the correct choice in this context.
