In a Lagrangian system, the position of a fluid particle in a flow is ...
In a Lagrangian system, the position of a fluid particle in a flow is described as x = x0e^(u*t), where x is the position of the particle at time t, x0 is the initial position of the particle, and u is the velocity of the particle. This equation describes how the position of the particle changes over time as it moves with the flow.
