Fluid Mechanics Quiz

What is the pressure exerted by gas particles on the walls of a balloon called?

• Absolute pressure

• Atmospheric pressure

• Gauge pressure

• Vacuum pressure

What is the relationship between absolute pressure and gauge pressure?

• Pabs = Patm - Pgage

• Pabs = Patm + Pgage

• Pabs = Pgage / Patm

• Pabs = Patm * Pgage

If the gauge pressure of an automobile tire is 32.0 psi and the atmospheric pressure is 14.3 psi, what is the absolute pressure?

• 46.3 psi

• 78.4 psi

• 32.0 psi

• 14.3 psi

What does a gauge pressure reading of 32.0 psi indicate?

• Pressure above absolute zero

• Pressure above atmospheric pressure

• Total pressure in the tire

• Pressure in a vacuum

At a depth of 8 m in water, if the absolute pressure is 175 kPa and the gauge pressure is 78.4 kPa, what is the local atmospheric pressure?

• 96.6 kPa

• 175 kPa

• 78.4 kPa

• 14.3 kPa
