    - THE STARTING POINT IS THE CONTINUITY EQUATION.

                                                 m = (X). A(X) . U(X)                                 (3.25)


  • FOR CONSTANT DENSITY


    U(X) 1 / A (X)

    •                   


                  (3.26)

     


    - THUS IN AN INCOMPRESSIBLE FLOW THE VARIATION OF VELOCITY WITH CROSS-SECTIONAL AREA IS :
