What is the maximum flow rate for a 1/2 inch pipe to stay below 5 feet per second?

The maximum flow rate for a 1/2 inch pipe to stay below 5 feet per second is determined by the relationship between flow rate, pipe diameter, and flow velocity. For a standard 1/2 inch pipe, if the flow exceeds a certain threshold, it can lead to problems such as increased friction loss, noise, and potential damage to the pipe system.

Flow velocity is typically calculated using the formula Q = A × V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity. For a 1/2 inch pipe, maintaining a flow velocity at or below 5 feet per second ensures that the flow remains efficient and does not create excessive turbulence or erosion within the pipe.

When calculating the flow rate associated with this velocity constraint, the answer that maintains the flow below this threshold is indeed 5 gallons per minute (gpm). This flow rate strikes a balance between efficiency and safety for the 1/2 inch pipe under the specified conditions. Higher flow rates would result in the velocity exceeding 5 feet per second, which could lead to various complications in an irrigation system.

Understanding these relationships is crucial for the design and maintenance of irrigation systems, as they affect
