Pipe Elevation Changes and Effect on Pressure Loss

Conversely, at the bottom of the vertical pipe there is the full weight of fluid in the pipe 'pushing down' on that point and due to this, the pressure at that point increases (in comparison to the pressure on the fluid at the top of the pipe).

Pressure measurement - Wikipedia

Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum.Instruments used to measure and display pressure in an integral unit are called pressure gauges or vacuum gauges.
