What is are the uses of piezometer Mcq?

Piezometer is used to measure Pressure in pipe channels etc. at a point. As one end is open to the atmosphere so it can’t be used for measuring the gas pressure (or atmospheric pressure).

What are advantages of piezometer?

Advantages and application One of the main application of piezometer is that it is used to measure pore water pressure/ ground water level. They are helpful in calculations to find performance of soil and rock.

How do standpipe piezometers work?

The Standpipe Piezometer is capable of measuring the borehole water level or water pressure at the piezometer tip. The water pressure at the filter tip is derived by measuring the height of the water surface in the riser pipe above the piezometer tip.

What are the types of piezometer?

Types of Piezometers

• Standpipe Piezometers. The standpipe piezometer is the most basic type of piezometer.
• Vibrating Wire Piezometers. The vibrating wire piezometer is the most commonly deployed type of piezometer.
• Pneumatic Piezometers. The pneumatic piezometer operates by gas pressure.

Where is piezometer installed in dam?

Installation in a concrete dam takes place with several piezometers that are installed at a chosen elevation at different cross-sections, along with other sensors.

What the liquid used in manometers should have?

Detailed Solution. The liquid used in manometers should have high density so that the height of the column can be reduced. Because the manometers are used for high-pressure measurement, so it is important to make the column height in a practical limit.

What is piezometer & its limitations?

The disadvantages of piezometers are: (1) Cannot measure vacuum pressure since air would be sucked into the container through the tube. (2) The measured pressure should be reasonably low, otherwise a very long vertical tube is needed. Manometer. Another pressure measuring device is the manometer.

What are the advantages and disadvantages of manometers?

Advantages and disadvantages of manometer

• It has a low cost.
• The manometer is suitable for low-pressure applications.
• It is simple in construction.
• It has better sensitivity.
• It has good accuracy.
• It has simple operation and construction.

How are piezometers installed?

Vibrating Wire Piezometer is installed in a borehole using a fully grouted method. Using a traditional method involves the placement of sand pockets surrounding the piezometers, grout columns, and bentonite seals to separate piezometers at different levels.

How the piezometers are used to measure the spot pressure in a pipeline?

A piezometer is either a device used to measure liquid pressure in a system by measuring the height to which a column of the liquid rises against gravity, or a device which measures the pressure (more precisely, the piezometric head) of groundwater at a specific point.

Where is piezometer installed?

The piezometer is to be installed/constructed at the minimum of 50 m distance from the pumping well through which groundwater is being withdrawn. The diameter of the piezometer should be about 4” to 6”. The depth of the piezometer should be same as in case of the pumping well from which groundwater is being abstracted.
