**Transcription and Explanation:**

*Problem Description:*

Water flows in a pipe of 1-inch diameter at a temperature of 70°F. The pressure values at points 1 and 2 are found to be 20 psi and 25 psi, respectively. The elevation of point 1 is 12 feet, and the elevation of point 2 is 0 feet. There are 15 feet of pipe between the two points. 

**Determine the direction of flow.**

- ( ) flow is from point 1 to point 2
- ( ) flow is from point 2 to point 1
- ( ) water does not flow between point 1 and point 2

*[continued from previous question]*

Water flows in a pipe of 1-inch diameter at a temperature of 70°F. The pressure values at points 1 and 2 are found to be 20 psi and 25 psi, respectively. The elevation of point 1 is 12 feet, and the elevation of point 2 is 0 feet. There is 15 feet of pipe between the two points.

**What is the minimum discharge above which the flow will not be laminar?** Report your answer in gallons per minute (gpm) with 2 decimal places.

*Explanation of Symbols and Terms:*

- **Pressure (psi):** Pounds per square inch, a unit of pressure.
- **Elevation (feet):** Height above a reference point, typically sea level.
- **Flow Direction:** Indicates the direction in which the water is flowing in the pipe.
- **Minimum Discharge (gpm):** The flow rate threshold above which the flow transitions from laminar to turbulent.

*Note:* The document does not contain graphs or diagrams.
