The pressure less than atmospheric pressure is known as
- water pressure
- absolute pressure
- gauge pressure
- vacuum pressure
Answer: 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
