How is pressure typically measured in water systems?

In water systems, pressure is commonly measured in pounds per square inch (psi) because it provides a practical way to express pressure levels that are relevant to everyday applications. This unit is particularly favored in the United States and is widely used in various engineering and plumbing applications, allowing operators and technicians to easily understand and communicate pressure levels within the system.

While other units like Pascals, bars, and kilopascals are also used in different contexts, psi is often the most familiar and convenient for those working directly with water treatment and distribution systems in certain regions. Its widespread use in industry standards makes it a practical choice for indicating pressure in pipes, tanks, and other components of water systems.
