When a manometer is connected to a fluid system, the liquid in the U-shaped tube settles to a level that reflects the pressure difference. This concept is fundamental in determining pressure head.

Specific gravity, a dimensionless property, is defined as the ratio of fluid density to the density of a reference fluid (usually water). By leveraging pressure head measurements in manometers, we can indirectly determine the specific gravity of a fluid.

For instance, if a manometer measures a pressure head of 0.5 meters in a fluid, and the reference fluid (water) has a density of 1000 kg/m³, we can calculate the specific gravity as follows:

Specific Gravity = (Pressure Head * Liquid Density) / (Reference Fluid Density)

Specific Gravity = (0.5 m * Liquid Density) / 1000 kg/m³

To determine the actual liquid density, we need to know the specific gravity. However, if we have a reasonably accurate estimate of the liquid density, we can use the manometer measurement to calculate the specific gravity.

Understanding the interplay between pressure head and specific gravity is vital for engineers and technicians in fields such as hydrology, process control, and fluid power systems.
