Understanding Pressure in Fluids

What is pressure defined as in relation to an object?

• The perpendicular weight on the surface divided by area

• The total weight of an object

• The force exerted by an object

• The weight of a fluid

How does fluid pressure change with depth?

• It decreases with depth

• It remains constant

• It increases with depth

• It is not affected by depth

What is the equation used to calculate pressure?

• P = F/A

• P = W/A

• P = ⍴×g×h

• P = F×A

What does the symbol P denote?

• Pressure

• Force

• Area

• Weight

What is liquid pressure directly related to?

• The depth of the liquid

• The temperature of the liquid

• The color of the liquid

• The shape of the container

What is the formula for liquid pressure?

• Liquid pressure = ⍴×g×h

• Liquid pressure = P×A

• Liquid pressure = F/A

• Liquid pressure = W/A

What is absolute pressure?

• Measured at pressure level zero

• Measured relative to atmospheric pressure

• Calculated when gauge pressure is negative

• Always greater than gauge pressure

What happens to pressure in a fluid at absolute zero acceleration?

• It becomes dependent on gravity

• It increases

• It decreases

• It remains constant

What is the relationship between pressure and the weight of an object?

• Pressure is directly dependent on weight

• Pressure is inversely dependent on weight

• Pressure is not related to weight

• Pressure increases with weight

What is the maximum pressure found in a fluid column?

• At the surface level

• At the bottom of the container

• In the middle of the container

• It is uniform throughout
