    can anybody please clearly explain me the difference between these two frames of reference with few examples.

    my exames are closing up. please help me.

    Lagrangian description - while calculating the trajectory of a projectile, you calculate all the parameters for the point mass moving in XY plane, that is Lagrangian description.

    Eulerian description - while solving a problem of continuity in a variable section channel, you calculate(velocity, pressure etc) all the parameters on various cross sections(or points), that is eulerian description of frame
