Answer :
Final answer:
The appropriate instrument for measuring pressure in a piping system is a Bourdon tube gauge. Other options include tachometers, thermocouples, and dial indicators, which are designed for different measurements. Bourdon tubes are versatile and used widely in engineering for pressure applications.
Explanation:
Measuring Pressure in a Piping System
To measure pressure in a piping system, the correct instrument is a Bourdon tube gauge (Option B). A Bourdon tube is a pressure-measuring device that operates based on the principle that an increase in pressure causes the tube to change shape. This change can then be converted into a readable measurement, typically displayed on a gauge dial. They can be used for a wide range of pressures from 0.1-700 MPa, making them suitable for various applications in engineering.
In contrast, the other options serve different purposes:
- A tachometer measures rotational speed and is not suitable for pressure measurement.
- A thermocouple measures temperature, not pressure.
- A dial indicator is used for measuring small distances rather than fluid pressure.
