Question

Inclined manometer is used for

• A. determining high pressure
• B. determining low pressure
• C. determining small differences in pressure
• D. highly viscous liquids

Hint:

Inclined manometers provide higher precision for small pressure differences compared to vertical ones.

Answer 1

The Correct Option is C

Inclined manometers are typically used for measuring small differences in pressure, especially when a more sensitive measurement is require(D) The inclination enhances the sensitivity by spreading the pressure difference along a longer length of fluid column. 
Conclusion: Inclined manometers are ideal for measuring small pressure differences due to their increased sensitivity.
