What is the minimum pipe size allowed for a water column?

The minimum pipe size allowed for a water column is typically set at 1 inch to ensure sufficient flow and pressure for various applications in stationary engineering. Using a 1-inch pipe size helps to reduce the risk of pressure losses and ensures that the water column can deliver adequate performance in systems such as heating, cooling, or any other equipment that relies on water for operational purposes. Smaller pipe sizes may not effectively handle the necessary water flow and could lead to operational issues such as increased friction losses, potential for cavitation, and insufficient supply to connected systems.

This standard is often based on plumbing codes and best practices within the industry, which consider factors such as flow rate, pressure drop, and the specific requirements of the equipment being supplied. A larger diameter pipe, like the 1-inch size, strikes a balance between ease of installation, cost-effectiveness, and performance.
