Query: Lagrangian Description in the context of Emergent spacetime   We make use of the Lagrangian description of fluid motion to highlight
certain features in the context of spacetime geometry as emergent phenomena in
fluid systems. We find by using Lagrangian Perturbation Theory (LPT), that not
all kind of perturbations on a steady state flow can produce analogue spacetime
effect. We also explore the manifold structure of emergent spacetime by using
the Lagrangian description of fluid motion. We restrict ourselves to
nonrelativistic flows.
