1. In a moving fluid, “static pressure” refers to:

Pressure caused only by temperature

The pressure a fluid exerts on a surface moving with the fluid

Only pressure due to speed

Only pressure due to height

Static pressure is the thermodynamic pressure at a point in the flow. It is what you would measure if you moved with the fluid and didn’t disturb it.

Explanation

Static pressure is the thermodynamic pressure at a point in the flow. It is what you would measure if you moved with the fluid and didn’t disturb it.

2. A moving fluid can have different pressures at different points even at the same height.

True

False

Flow speed changes and losses can create pressure differences. Unlike pure hydrostatics, motion adds additional effects.

Explanation

Flow speed changes and losses can create pressure differences. Unlike pure hydrostatics, motion adds additional effects.

3. “Dynamic pressure” is most closely associated with:

Density only

The kinetic energy of the moving fluid

Colour of the fluid

The container’s mass

Dynamic pressure represents the “speed-related” contribution to pressure-like energy. Faster flow corresponds to larger dynamic pressure.

Explanation

Dynamic pressure represents the “speed-related” contribution to pressure-like energy. Faster flow corresponds to larger dynamic pressure.

4. A point where flow speed is reduced to zero (in the flow) is called a ______ point.

At a stagnation point, fluid comes to rest, converting kinetic energy into pressure. This is useful for measuring speed with pressure instruments.

Explanation

At a stagnation point, fluid comes to rest, converting kinetic energy into pressure. This is useful for measuring speed with pressure instruments.

Submit

5. Stagnation pressure is typically higher than static pressure at the same point upstream (in ideal conditions).

True

False

When speed drops to zero, kinetic energy becomes pressure energy. This raises the measured pressure at the stagnation point compared with static pressure.

Explanation

When speed drops to zero, kinetic energy becomes pressure energy. This raises the measured pressure at the stagnation point compared with static pressure.

6. A pitot tube is used primarily to measure:

Fluid temperature

Flow speed using pressure difference

Fluid colour

Surface roughness

A pitot tube measures stagnation pressure at its opening and compares it to static pressure. The difference relates to the flow’s speed.

Explanation

A pitot tube measures stagnation pressure at its opening and compares it to static pressure. The difference relates to the flow’s speed.

7. In many flows, pressure drop along a pipe can occur due to friction and turbulence.

True

False

Viscous effects convert mechanical energy to heat. This causes pressure to decrease along the direction of flow.

Explanation

Viscous effects convert mechanical energy to heat. This causes pressure to decrease along the direction of flow.

8. Which statement best describes why “pressure energy” can be thought of as useful in fluid systems?

Pressure has no effect on motion

Pressure differences can drive fluid flow and do work

Pressure is only a unit conversion

Pressure always cancels out

Fluids flow from higher to lower pressure when a path exists. Pressure can also exert forces that do mechanical work (e.g., pistons).

Explanation

Fluids flow from higher to lower pressure when a path exists. Pressure can also exert forces that do mechanical work (e.g., pistons).
