                 Example 2.6
                 If the diameter d = 15 cm and the mean velocity, v = 3 m/s, calculate the actual discharge in the pipe.

                 Solution:
                                                           =   ×

                                                              ²
                                                          =     ×
                                                             4
                                                           × (0.15)
                                                      =             × 3
                                                             4

                                                         = 0.053   /



               2.3.5   Continuity Equation














                                                  Fig. 8: Principle of continuity


               Another example in the use of the continuity principle is to determine the velocities in pipes coming from a
               junction.


                               Total discharge into the junction = Total discharge out of the junction

                                                        Q1 = Q2 + Q3

                                                     A1v1 = A2v2 + A3v3
