The liquid used in manometers should have?

By Raj Vimal|Updated : October 13th, 2022

(A) Low density

(B) High density

(C) Low surface Tension

(D) High surface tension

The liquid used in manometers should have high density. To lower the column height, the manometers liquid must have a high density. Making the column height a reasonable limit is critical since manometers are used to measure high pressures.

Manometer classification

A manometer monitors the pressure of fluids. Manometers are categorized into numerous varieties based on a number of factors. As follows:

  1. U-Tube Manometer
  2. Well-Type Manometer
  3. Enlarged-Leg Manometer
  4. Inclined-Tube Manometer

Mercury is frequently employed as a manometric fluid for gauge pressure measurements because it exhibits non-evaporating properties under typical conditions, a distinct meniscus, and constant density. Water can be regarded as the manometer's working fluid for some pressure differentials and low-level vacuum.

  • For greater reading accuracy, manometric fluid should have a low surface density.
  • Although having low surface tension is a good quality, being highly densified is the most crucial quality.

Summary:

The liquid used in manometers should have? (A) Low density (B) High density (C) Low surface tension (D) High surface tension.

High density liquid should be utilised in manometers. The liquid used in manometers must be highly dense in order to reduce the column height. Given that manometers are used to measure high pressures, it is essential to set an appropriate upper limit for the column height.
