When comparing water flow through pipes of different diameters at the same pressure, a 1.25" pipe typically allows for a maximum flow of about 30-40 gpm, while a 10" pipe can handle around 2500-3000 gpm. However, actual flow rates depend on various factors such as outlet pressure, fittings, elevation changes, pipe material, and fluid type. The relationship between pipe diameter and flow is not linear; doubling the diameter results in a flow increase of four times, not double. Without additional details, precise flow rates cannot be determined. Understanding these dynamics is crucial for accurate fluid flow assessments.
