Scenario: You are designing a new pipeline to transport natural gas from a production well to a processing plant. The well produces 1 million cubic feet of natural gas per day (MMcfd), and the pipeline will be 10 miles long.
Task:
Here's a possible approach to solving the exercise: 1. **Research:** - Typical flow velocities for natural gas pipelines range from 5 to 15 feet per second. - Factors influencing flow velocity include: - Pipeline size (ID) - Gas density and viscosity - Pressure drop - Friction losses 2. **Calculate:** - Let's assume a target flow velocity of 10 feet per second. - We need to find the cross-sectional area of the pipeline required to transport 1 MMcfd at this velocity. - Convert 1 MMcfd to cubic feet per second: 1 MMcfd / (24 hours/day * 3600 seconds/hour) = 0.0116 cubic feet per second. - Use the formula: Flow rate (Q) = Velocity (V) * Cross-sectional area (A) - Rearrange to find area: A = Q / V = 0.0116 cubic feet per second / 10 feet per second = 0.00116 square feet. - Convert area to square inches: 0.00116 square feet * 144 square inches/square foot = 0.167 square inches. - Find the diameter: A = π * (D/2)^2, where D is the diameter. Rearranging, D = 2 * sqrt(A/π) = 2 * sqrt(0.167 square inches / π) = 0.46 inches. - Therefore, the estimated required ID of the pipeline is approximately 0.46 inches. 3. **Explain:** - A larger ID would result in a lower flow velocity, reducing pressure drop and increasing efficiency. However, it would also mean a larger, heavier, and more expensive pipeline. - A smaller ID would lead to higher flow velocity, potentially increasing pressure drop and reducing efficiency. It could also lead to higher frictional losses. - The chosen ID balances these factors to ensure safe and efficient gas transportation.
