Which of the following statements regarding piezometer is incorrect?a...
A piezometer is an open vertical tube attached to a gauge point to measure it’s pressure.
∴ pA = ρgh
In case of vacuum, the atmospheric air from outside will seep inside disturbing the system. Hence vacuum pressure cannot be measured.
In case of gases, a free surface is not formed and reading is not obtained.
In case of high pressure, the required length of the piezometer tube is very long making it unsuitable for use.

Piezometers and their Measurement Capabilities
Piezometers are devices that are used to measure the pressure of liquids in a confined space. They are commonly used in geotechnical engineering, hydrology, and civil engineering. Some of their measurement capabilities are as follows:
• Piezometers can measure pressure of liquids, not gases: Piezometers are designed to measure the pressure of liquids, not gases. Therefore, they cannot measure the pressure of gases.
• Piezometers cannot measure vacuum: Piezometers are designed to measure pressure in a confined space, but not in a vacuum. Therefore, they cannot measure vacuum.
• Piezometers are suitable for measuring high pressure: Piezometers can measure high pressures, but the range of measurement depends on the type of piezometer used.
• None of the above statements are incorrect: All of the statements mentioned above are true, and they highlight the measurement capabilities of piezometers.
Conclusion
In conclusion, piezometers are valuable tools in the field of civil engineering, geotechnical engineering, and hydrology. They have the ability to measure pressure in liquids in a confined space, and are hence used in many applications. However, it is important to note that piezometers cannot measure gas pressure or vacuum.
