The pressure less than atmospheric pressure is known as

1. water pressure
2. absolute pressure
3. gauge pressure
4. vacuum pressure

## The pressure less than atmospheric pressure is known as vacuum pressure.

Explanation:

• Absolute pressure- The pressure difference is known as absolute pressure when absolute zero is chosen as the datum.
• Gauge pressure– The gauge pressure is the pressure that exists when the pressure is greater than the atmospheric pressure.
• Vacuum pressure-The vacuum pressure is the pressure that exists when the pressure is lower than the atmospheric pressure.

The relationship between the pressures is given by,

Absolute pressure = Atmospheric pressure + Gauge pressure

Pabs=Patm+Pgauge

Vacuum pressure = Atmospheric pressure – Absolute pressure

Pvac=Patm-Pabs
