How to calculate flow & pressure through branched pipes from header line with known flow & pressure?illustrate

Sounds like a continuity problem.

Do you need to take losses into account or is it strictly an application of Bernoulli’s Equations?

Is this for fluids or gasses?

Dear Leon,

Suppose we are considering practical approach for media water.
I have 6 inch water pipe with known flow and pressure, running horizontaly at 10 meter height. Now suppose, I took two tappings from this pipe. One is of 2 inch dia and other is 3 inch dia. Tappings are 10 meter apart and desending downward from this 6″ horizontal pipe. open end of 2″ and 3″ tappings are fixed with isolation ball valves. how I can calculate the Flow and pressure at these two tappings before isolation valves. what flow and pressure changes in 3″ tapping if i opened 2″ tapping valve.
Please illustrate step by step, so that i can apply the same logic in bigger pipe network.

This is a application of Bernoulli’s Principle [1] and [2] to an incompressible fluid and the continuity principle [2].
