How is pressure in fluid systems often measured?

Pressure in fluid systems is typically measured in feet of water column because this measurement provides a practical way to express the pressure exerted by a column of water due to gravity. This unit effectively represents the hydrostatic pressure that a fluid exerts at a given depth. When you measure pressure in terms of the height of a water column, it allows for easy comparison to other fluids, as the pressure can vary based on the fluid's density.

Using feet of water column is a common practice in many engineering and wastewater applications, as it relates directly to the pressure that fluids exert in systems such as pipelines and treatment plants. This method simplifies calculations and helps technicians determine how much pressure is needed for proper flow and the operation of equipment in fluid systems.
