Calculating flow through parallel pipes

AI Thread Summary
To calculate flow through two parallel pipes, the pressure drop (delta P) is equal for both streams, and flow is determined by the resistance in each pipe. The resistance can be calculated using the diameter and flow velocity, which is derived from the cross-sectional area of the pipes. However, without additional information about the flow rate or pressure, it's challenging to determine the velocity accurately. The discussion highlights the need for more data to complete the calculations effectively. Understanding these principles is crucial for solving parallel pipe flow problems.

Homework Statement



I am trying to calculate the flow through two parallel pipes. From an 8in line, a 1in line T's off and then joins back together downstream.

How do I go about solving a problem like this? The delta P should be equal for both streams so the flow should be determined by the resistance in the pipe, correct? I am having trouble calculating the resistance in the pipe...

Flow (Q) is the velocity times the area.

Since you have the diameter of the pipe you can find the cross-sectional area then all you need is the velocity.

With what you've given so far I don't see a way to calculate the velocity. Are you leaving something out.?
