Question

Which of the following is NOT an ideal instrument to measure the pressure inside a closed container?

• A. Diaphragm Pressure Gauge
• B. Inclined manometer
• C. Venturimeter
• D. Piezometer

Answer 1

Answer:

C. Venturimeter

A venturimeter is not an ideal instrument to measure pressure inside a closed container as it is used to measure the discharge of only internal flow. Diaphragm pressure gauge, inclined manometer, and piezometer are ideal instruments for measuring pressure. A diaphragm gauge uses a flexible membrane to measure pressure, while an inclined manometer measures pressure using a column of liquid. A piezometer measures pressure at a single point in a fluid using a tube inserted into the fluid.
