Pipeline Flow Calculation Consultation

What is the flow rate in Pipeline 1?

A. 5.0
B. 10.0
C. 12.9
D. 15.0

Answer:

We cannot determine the flow in Pipeline 1 without knowing the slope of the pipe.

To calculate the flow in Pipeline 1, we need to consider various factors such as the pipe diameter, length, slope, and the Hazen-Williams C value. In this case, Pipeline 1 has an 18-in. diameter and is 2,400 ft long with a Hazen-Williams C of 130. As mentioned in the question, the branched pipes join at Point B to a 24-in. pipe, but the slope of the pipe is not given.

The flow rate in Pipeline 1 can be calculated using the Hazen-Williams equation:

Q = (C * A * R^(2/3) * S^(1/2)) / L

Where:

Q is the flow rate

A is the cross-sectional area of the pipe

R is the hydraulic radius

S is the slope of the pipe

L is the length of the pipe

Given the diameter of Pipeline 1, we can calculate the cross-sectional area and the hydraulic radius. However, without the slope of the pipe, we cannot determine the flow rate accurately.

Therefore, to accurately calculate the flow rate in Pipeline 1, we need to know the slope of the pipe. Without this crucial information, we cannot provide a definitive answer. For further details on how to calculate flow in pipelines, you can refer to the link provided in the question.
