I can see that you've uploaded a fluid mechanics quiz. Let's go through the image to provide some insights:

### Identification (Conceptual Questions):
1. **Pressure measured above or below atmospheric pressure** is called **gauge pressure**.
2. **Barometer** is a device for measuring **atmospheric pressure**.
3. The **pressure of a fluid in a gravity field** is usually calculated using **manometer**.
4. **U-tube manometer** is designed to contain fluids of different specific gravities for pressure measurement.
5. The principle of **absolute pressure** indicates that pressure applied to a confined fluid is transmitted undiminished in all directions.
6. **Pressure head** represents the height of a fluid column.
7. **Absolute pressure** includes atmospheric pressure plus the pressure within the confined space.
8. Pressure acting at a point in a fluid is the same in all directions—**Pascal's law**.
9. **Pressure** is defined as the **force per unit area** on a surface.

### Computation (Mathematical Problems):
1. For the computations regarding pressures in pipes and tanks:
   - The fluid density (based on given figure data at 20°C).
   - Determine pressures at different points using standard fluid mechanics equations.
   
2. Analyzing small pressure changes:
   - If you need to compute pressure differences at points A and F, you'd apply Bernoulli's principle or the hydrostatic pressure formula.

3. **Conical tank** calculations:
   - Volume of the conical tank = \( V = \frac{1}{3} \pi r^2 h \).
   - Given radius and height, fill the tank with water and calculate total volume.

4. **Tank and drainpipe problem**:
   - Use the densities provided for gasoline and glycerin and apply hydrostatic pressure formulas to find the pressure at the plug C in the pipe.

5. **Drum with vertical pipe**:
   - You'd apply basic pressure formulas to compute how much force water will exert on the drum based on the water height and cross-sectional area of the pipe.

If you'd like me to walk through any specific problems or calculations step by step, feel free to point out which one!

### Expanding Questions:
1. How is gauge pressure different from absolute pressure?
2. How do you calculate hydrostatic pressure in fluids with different densities?
3. What are the effects of gravity on pressure in a vertical fluid column?
4. How does Pascal’s law apply to real-world hydraulic systems?
5. How does the shape of a tank affect the total volume calculation?

**Tip**: Always double-check the units when calculating pressure or force, as inconsistencies can lead to errors in final results.
