Here's how to calculate the velocity in feet per second (fps) for the given flow rate through a 10-inch pipe:

1. Convert Gallons per Minute (GPM) to Cubic Feet per Second (CFS)

* 1 gallon = 0.1337 cubic feet

* 1 minute = 60 seconds

Therefore:

* 722 GPM * (0.1337 ft³/gallon) * (1 minute / 60 seconds) ≈ 1.61 CFS

2. Calculate the Cross-Sectional Area of the Pipe

* Pipe diameter = 10 inches = 10/12 feet = 0.833 feet

* Area = π * (diameter/2)²

* Area = π * (0.833/2)² ≈ 0.545 square feet

3. Calculate the Velocity

* Velocity = Flow Rate / Area

* Velocity ≈ 1.61 CFS / 0.545 ft² ≈ 2.96 feet per second (fps)

Therefore, the velocity of the flow through the 10-inch pipe is approximately 2.96 feet per second.
