Question

measures heat loss from a heated wire to measure pressure.

• A. Orifice meter
• B. Manometer
• C. Pirani gauge
• D. Barometer

Answer 1

Answer:

C. Pirani gauge

Pirani gauge measures pressure by measuring heat loss from a heated wire to the gas media. The manometer measures the difference in pressure between two points using columns of liquid. An orifice meter is a cylindrical tube with a thin hole to force fluid to flow faster. Barometer measures local atmospheric pressure using a mercury column
