What does a barometer measure?
Think about the weather and atmospheric conditions.
What is gauge pressure?
Consider how we measure pressure in different contexts.
What does a barometer primarily measure?
Think about devices you might use when checking the weather.
True or False: Gauge pressure accounts for atmospheric pressure.
Remember what 'gauge' means in this context.
A pressure transducer indicates a gauge pressure of 600 kPa. If the local atmospheric pressure is 100 kPa, what is the absolute pressure?
Remember to add the atmospheric pressure to the gauge pressure.
Determine the height of mercury needed to measure a pressure of 1 MPa using a manometer. (Take density of mercury = 13,600 kg/m³)
Use the mercury density to find the height in a manometer.
