Questions & Step-by-Step Solutions

What is the principle behind a manometer? (2023)
  • Step 1: Understand that a manometer is a device used to measure pressure.
  • Step 2: Know that it compares the pressure of a fluid at one point to the pressure at another point.
  • Step 3: Realize that it usually consists of a U-shaped tube filled with liquid (like water or mercury).
  • Step 4: Observe that when pressure is applied to one side of the tube, the liquid level changes.
  • Step 5: Measure the difference in height of the liquid in the two sides of the tube to find the pressure difference.
