Altitude is a factor that may be important parameters of a network Pumping .

When altitude increases, the atmospheric pressure decreases.

A liquid boils when its pressure saturated vapor exceeds the ambient pressure.

Pressure drop can cause the boiling of the liquid without changing its temperature .

This happens in a pipe or a pump when the suction is too high. It is the pipe or pump cavitation.

The atmospheric pressure drop is usually not sufficient to cause cavitation in a network Pumping, but a system sized to operate at sea level could cavitating if it is installed in the same configuration at 3000 meters of altitude

Altitude is a parameter to include in the tab system of pumps and turbines,

value of ambient pressure is thus proposed according to the temperature
