Steady Flow: The flow is defined as steady flow when the velocity and other hydrodynamic parameters do not change with time at any given point.
Unsteady Flow: The flow is defined as unsteady flow when the velocity and other hydrodynamic parameters change with time at any given point.
Uniform flow: The flow is defined as uniform flow when the velocity and other hydrodynamic parameters do not change from point to point at any given instant of time.
Non-uniform flow: The flow is defined as non-uniform flow when the velocity and other hydrodynamic parameters change from point to point at any given instant of time.
The given function of u = x + 2t
u = f (x,t)
u is a function of both time and space. Therefore the velocity will vary with time as well as space. Hence it is unsteady and non-uniform flow.Last updated on May 28, 2025
