For a 1 inch pipe, what is the maximum flow rate to ensure it stays below 5 feet per second?

• A. 10 gallons per minute
• B. 15 gallons per minute
• C. 25 gallons per minute
• D. 35 gallons per minute

Answer: (B)

To determine the maximum flow rate for a 1-inch pipe that keeps the velocity below 5 feet per second, it is important to utilize the relationship between flow rate, pipe diameter, and fluid velocity. A 1-inch diameter pipe has specific flow characteristics governed by its diameter. The flow velocity (in feet per second) can be calculated using the formula: \[ Q = A \times v \] Where: - \( Q \) is the flow rate (in cubic feet per second), - \( A \) is the cross-sectional area of the pipe (in square feet), - \( v \) is the velocity (in feet per second). For a 1-inch diameter pipe, the cross-sectional area can be calculated as follows: The radius (in feet) is: \[ r = \frac{1 \text{ inch}}{2} = \frac{1 \text{ inch}}{12 \text{ inches/foot}} = \frac{1}{24} \text{ feet} \] The area \( A \) is then: \[ A = \pi r^2 = \pi \left( \frac{1}{24} \right)^2 \approx 0.052

To determine the maximum flow rate for a 1-inch pipe that keeps the velocity below 5 feet per second, it is important to utilize the relationship between flow rate, pipe diameter, and fluid velocity.

A 1-inch diameter pipe has specific flow characteristics governed by its diameter. The flow velocity (in feet per second) can be calculated using the formula:

[

Q = A \times v

]

Where:

• ( Q ) is the flow rate (in cubic feet per second),

• ( A ) is the cross-sectional area of the pipe (in square feet),

• ( v ) is the velocity (in feet per second).

For a 1-inch diameter pipe, the cross-sectional area can be calculated as follows:

The radius (in feet) is:

[

r = \frac{1 \text{ inch}}{2} = \frac{1 \text{ inch}}{12 \text{ inches/foot}} = \frac{1}{24} \text{ feet}

]

The area ( A ) is then:

[

A = \pi r^2 = \pi \left( \frac{1}{24} \right)^2 \approx 0.052
