**Title: Calculating Effective Velocity and Travel Time in a Sand-Filled Darcy Tube**

**Objective:**
Use the information provided and the figure below to determine the effective velocity of water through the sand-filled Darcy tube. Also determine how many hours the water will take to flow from one end of the sand-filled tube to the other (travel the distance between \(x_1\) and \(x_2\)).

### Instructions:

- **Step 1:** You will need to perform several calculations to determine the effective velocity.
- **Step 2:** For each calculation, write the equation.
- **Step 3:** Fill in the values for each variable with units.
- **Note:** Provide all answers with proper units. Since you are dealing with a small distance, provide your final effective velocity units in cm/hour. You can provide your travel time in decimal hours (e.g., 2.5 hours, rather than 2 hours and 30 minutes).

### Diagram Explanation:

- The diagram features a U-shaped apparatus.
- **Left Side:**
- Water is shown entering from the top.
- The height (\(h_1\)) from the reference level to the water is 33 cm.
- **Center Section:**
- Contains sand, labeled as "Sand."
- Marked distance between \(x_1\) to \(x_2\) is 30 cm.
- The horizontal area of the sand-filled section is labeled as "Area A."
- **Right Side:**
- Water is shown exiting from the top.
- The height (\(h_2\)) from the reference level to the water is 27 cm.

### Given Data:

- **Area of sand-filled tube:** 735 cm²
- **Hydraulic conductivity of sand:** 40 m/day
- **Effective porosity:** 0.45

**End of Instructions.**

Use the information and equations learned to calculate and answer the given tasks.
