## Sample Problem on Hydraulic Conductivity

### Problem 12
15 cm³ of water flows through the soil sample shown in the figure within 4 minutes. Calculate the hydraulic conductivity of the soil sample. The cross-sectional area of the sample is 12 cm². Assume necessary conditions as given.

The figure illustrates a soil column with the following dimensions:
- The total height of the soil is 37 cm.
- Within this height, 30 cm is the length of the soil portion to be considered for flow.
- An additional setup is perpendicular to the right side of the soil column, with a lower height of 12 cm displayed.

> **Note:** All measurements are provided in centimeters.

### Problem 13
For the same problem as above, determine the following at the midpoint of the sample after 2 minutes:
a. \( h_t = \_\_\_\_\_\_ \) cm  
b. \( h_e = \_\_\_\_\_\_ \) cm  
c. \( h_p = \_\_\_\_\_\_ \) cm 

> The variables represent:
> - \( h_t \): Total head
> - \( h_e \): Elevation head
> - \( h_p \): Pressure head 

### Diagram Explanation
The provided diagram shows a vertical soil sample with specific marked heights, illustrating the areas for calculation in the problem. The setup adjacent to the soil column is relevant for understanding pressure and flow direction, necessary for determining hydraulic properties and potential heads.
