Final answer:
The velocity of the flow is approximately 10.18 ft/s.
Step-by-step explanation:
The flow rate of a fluid can be determined using the equation:
Flow Rate = Area × Velocity
In this problem, the flow rate is given as 0.5 ft³/s and the diameter of the pipe is given as 3 inches. To find the velocity, we need to calculate the area of the pipe using the formula:
Area = π × (radius)²
Since the diameter is given, we can find the radius by dividing the diameter by 2. So, the radius is 1.5 inches or 0.125 feet.
Plugging in the values:
Area = π × (0.125)² = 0.049087 ft²
Now, we can rearrange the flow rate equation to solve for velocity:
Velocity = Flow Rate / Area = 0.5 ft³/s / 0.049087 ft² = 10.18 ft/s
Therefore, the velocity of this flow is approximately 10.18 ft/s.
