## Homework Statement

in this network of pipe , the author make the attempts to solve it using ( Q1 = Q2 + Q3) , so delta Q = Q1 -(Q2 +Q3) , the value of head of junction that he gt is 25.2 , with delta Q = (3x10^-3) ( not shown in the working)

## Homework Equations

## The Attempt at a Solution

however, when i tried to solve it using ( Q1 + Q2 = Q3) , which means ( Q1 +Q2 - Q3 ) , thae ans that i gt is hj = 28 , with delta Q = 0.07 [/B]

**P/s : we have to find the delta Q = 0 for the ans so that water from inlet = water from outlet**

so , question has two ans depending on the flow of water ??? or i am wrong ?
