Concept:
Differential Manometers:
- Differential manometers are devices used for measuring the difference of pressures between two points in a pipe or in two different pipes.
- A differential manometer consists of a U-tube, containing a heavy or light liquid, whose two ends are connected to the points, whose difference of pressure is to be measured.
- The most common types of differential manometers are
- U-tube differential manometer
- Inverted U-tube differential manometer
- The tube generally contains mercury or any other liquid whose specific gravity is greater than the specific gravity of the liquid whose pressure is to be measured.
U-tube differential manometer
- It consists of a U-tube containing a heavy liquid.
- The two ends of the tube are connected to the points whose difference is to be measured.
- It is used for measuring the difference of pressure between two points in the flow section to which it is connected.
Differential inverted U-tube manometer:
- It consists of an inverted U-tube containing a light liquid.
- The two ends of the tube are connected to the points whose difference is to be measured.
- It is used for measuring the difference of pressure between two points in the flow section to which it is connected.
- It is used in two conditions
- In underground pipeline
- When the specific gravity of manometric fluid is less than 1

Differential manometers are devices used to measure the difference in pressure between two different points in pipes or between different pipes. Let's break down the answer and explain it in detail.
1. Differential manometers:
- Differential manometers are instruments used to measure the difference in pressure between two different points.
- These devices are commonly used in various fields, including civil engineering, to monitor and control pressure differences in piping systems.
2. Measuring pressure difference:
- The primary purpose of a differential manometer is to measure the difference in pressure between two points.
- By comparing the pressure at two different locations, we can determine the pressure difference within a pipe or between different pipes.
3. Different points in the same pipe:
- Option (a) states that differential manometers can measure the pressure difference at different points in the same pipe.
- This is indeed correct. Differential manometers can be connected to two different points along a single pipe to measure the pressure difference between those points.
4. Same point in different pipes:
- Option (c) suggests that differential manometers can measure the pressure difference at the same point in different pipes.
- While this is technically possible, it is not the primary function of a differential manometer.
- Differential manometers are typically used to measure pressure differences between different points, rather than at the same point in different pipes.
5. Two different points in pipes or different pipes:
- Option (d) correctly states that differential manometers can measure the pressure difference between two different points in pipes or between different pipes.
- This is the most accurate and comprehensive answer.
- Differential manometers can be connected to different points in the same pipe or different pipes to measure the pressure difference between them.
In conclusion, differential manometers are devices specifically designed to measure the pressure difference between two different points in pipes or between different pipes. While they can also measure pressure differences at the same point in the same pipe, their primary function is to determine the pressure difference between different points or pipes.
