A one dimensional flow is one which
When a cylindrical vessel, containing some liquid, is rotated about its vertical axis, the liquid surface is depressed down at the axis of its rotation and rises up near the walls of the vessel on all sides. This type of flow is known as
Uniform flow occurs when
Two dimensional flow occurs when
Euler’s equations of motions can be integrated when it is assumed that
What is the type of flow when a cylindrical vessel containing some liquid is rotated about its vertical axis?
The flow of water in a wash hand basin when it is being emptied through a central opening, is an example of
Stream line, path line and streak line are identical when the
A flow in which fluid moves rapidly inwards towards a point where it disappears at a constant rate, is called as:
In a one-dimensional flow field in a pipe, the fluid velocity is given by u = x + 2t where ‘t’ is the time. The flow in the pipe is:
A velocity field is given as \(\vec V = \;Axy\hat i - \;Byzt\hat j\;\) where A and B are constants. x, y, z are in metre and t is in seconds. Which of the following is true of this flow field?
In hydrostatics, what would be the summation of the net forces acting on a fluid element?
A network of pipes conveying water to a city has the following specifications. The diameter of a main pipe is 30 cm and it branches into two pipes of diameters 20 cm and 15 cm respectively. If the average velocity in the main pipe is 2.5 m/s and the average velocity in the 20 cm pipe is measured as 2 m/s, what is the velocity in the 15 cm pipe ?
What various fluid particles move in Zig-Zag paths, flow is called:
What does a Lagrangian description of fluid flow provide?
