question 3

Explanation:

• Gauge Pressure: Gauge pressure measures the pressure above the ambient (atmospheric) pressure. So it matches "an instrument is reading and displaying pressure above ambient".
• Absolute Pressure: Absolute pressure includes the ambient (atmospheric) pressure along with the pressure being measured. So it matches "an instrument is reading and displaying pressure including ambient".
• Differential Pressure: Differential pressure is the difference between two pressures (measured at different locations or of different sources). So it matches "an instrument is reading and displaying the difference between two pressures read at different locations".

Answer:

• gauge pressure: an instrument is reading and displaying pressure above ambient
• absolute pressure: an instrument is reading and displaying pressure including ambient
• differential pressure: an instrument is reading and displaying the difference between two pressures read at different locations
