In summary, the drift velocity is the average velocity of the electrons that move randomly in the absence of an external field. Jun 6, 2013 #1 anhnha 181 1 I need help to understand the concept of drift velocity. Here is part from my book: Does this velocity refer to the velocity ...
What is the difference between flow rate and fluid velocity? How are they related? What Are Fluids? In fluid mechanics, a fluid refers to a substance that can flow and has the ability to deform under applied shear stress. It can include both liquids and gases. ...
1in m/s? (2)Whst is the pressure at section2in kPa? (3)What is the velocity at section3in m/s? (4)What is the pressure at section3in kPa? Figure P3.111 There are 3 steps to solve this one.

Fluid dynamics is the science of fluids that are in motion. The primary principles of fluid dynamics include the rule of...
What is the electric flux through (a) surface 1 (b) surface 2 ? Explain why fluid velocity is greatest where streamlines are closest together. (Hint: Consider the relationship between fluid velocity and the cross-sectional area through which it flows.) ...
Problems in fluid dynamics Scientists often try to visualize flow using figures called streamlines, streaklines and pathlines. McDonough defines a streamline as "a continuous line within a fluid such that the tangent at each point is the direction of the velocity vector at that point." In other...
Any fluid can be considered as incompressible under certain conditions on velocity and pressure. The tendency of a fluid to change volume when subjected to an external load depends on the material itself. For the sake of simplicity, let’s consider the common case of an elastic isotropic ...
a rock with the same weight. This is why an ant can fall off a tall building and land unharmed, while a similar fall would kill you. Keep in mind that this process happens in any gas or fluid. So terminal velocity defines the speed that a rock sinks when you drop it in the water...
