Manometers measure the ______________ pressure?
Correct answer: B. Difference in
- A. Vacuum as well as the atmospheric
- B. Difference in
- C. Absolute
- D. Gage
Explanation
A manometer balances the pressure difference between its connected points through the hydrostatic head of a manometric liquid. It therefore directly measures differential pressure, although gauge pressure can be obtained by connecting one side to the atmosphere.
