               Pipe Problems (2)
   Seoul National University
   Contents
   8.1 Multiple Pipes
   8.2 Three Reservoir Problems
   8.3 Pipe Networks
   Objectives
    Solve problems of multiple pipes 
    Learn methods to solve pipe network problems
       Seoul National University
     8.1 Multiple Pipes
   - In real world, pipe is not single but connected with others.
   - Sometimes, there are connections among hundred pipes.
   - Even though there are many pipes, basic principles are the same.
                                                                             3
       Seoul National University
   Two diverged pipes
    - Make problem simple, local loss and velocity head are neglected in the 
    Bernoulli eq. with the EL-HGL considered coincident.
    - As a consequence, the EL-HGLs of the pipes form a continuous network
    above the pipes, joining at the pipe junctions.
       → The head loss through both branches of the loop must be the same.
