Pipe and Riser Irrigation Systems | Irrigation | Soil and …

Many irrigators find pipe and riser systems operate in such a way they are under a lot more pressure when irrigating and eventually automate the system to alleviate this work load. This is especially important where flow rates have increased significantly.

GPM/GPH Flow based on PVC Pipe Size

The flow rates shown are for water, with viscosity of 1. Higher viscosity liquids will flow less, lower viscosity liquids may flow more. Note: One of the benefits of using Flex PVC pipe is being able to make long gradual bends instead of using fittings which will allow more flow with less noise, less back pressure, and less load on the pump.

How much water can flow through a pipe (GPM/GPH)?

We regularly get asked about the water flow capacity of different pipe sizes, and which is the best roof drain for a specific pipe size. Unfortunately, recommendations aren''t that straightforward because you also need to account for water pressure, material friction and
