Derivation Mechanical Energy

If we denote H as total energy head per unit weight then,

Along a streamline, the variation of H along the normal can be shown as,

        (14.8)

Now equation of motion for a streamline flow along the normal,

Using this equation,

Since,

Now for a streamline we have , so
