What is Reynolds transport theorem in fluid mechanics?

Reynolds transport theorem states that the rate of change of an extensive property N, for the system is equal to the time rate of change of N within the control volume and the net rate of flux of the property N through the control surface.

What is a Streakline in fluid mechanics?

streamline, In fluid mechanics, the path of imaginary particles suspended in the fluid and carried along with it. In steady flow, the fluid is in motion but the streamlines are fixed.

What are the different types of boundary conditions encountered in solving fluid flow problems?

These boundary conditions include inlet boundary conditions, outlet boundary conditions, wall boundary conditions, constant pressure boundary conditions, axisymmetric boundary conditions, symmetric boundary conditions, and periodic or cyclic boundary conditions.

What is the difference between streamlines and Streaklines?

A streamline is a line which smoothly connects velocity vectors at an instance in time. In other words, an image of the flow characterized by streamlines is like a snapshot of the flow at one moment in time. A streakline is a curved line formed by a string of fluid particles which have passed through a certain point.

What is the difference between Streamline and Pathline and streakline?

Streamlines, streaklines and pathlines are field lines in a fluid flow. They differ only when the flow changes with time, that is, when the flow is not steady. Streamlines are a family of curves that are instantaneously tangent to the velocity vector of the flow.

What is difference between steady flow and uniform flow?

A steady flow is the one in which the quantity of liquid flowing per second through any section, is constant. Steady flow may be uniform or non-uniform. Uniform flow. A truly uniform flow is one in which the velocity is same at a given instant at every point in the fluid.
