Torricelli’s law
E1487541
UNEXPLORED
Torricelli’s law is a principle in fluid dynamics that relates the speed of fluid flowing out of an orifice under gravity to the height of the fluid above the opening, analogous to the velocity of a freely falling object.

-
A.
Venturi effect
The Venturi effect is a fluid dynamics phenomenon in which a fluid's pressure decreases and its velocity increases as it flows through a constricted section of pipe or channel.
-
B.
Bernoulli equation
The Bernoulli equation is a fundamental principle in fluid dynamics that relates pressure, velocity, and elevation in steady, incompressible, inviscid flow along a streamline.
-
C.
Darcy’s law
Darcy’s law is a fundamental equation in fluid mechanics that relates the volumetric flow rate of a fluid through a porous medium to the pressure gradient, permeability, and fluid viscosity.
-
D.
Pascal's law
Pascal's law is a fundamental principle of fluid mechanics stating that pressure applied to an enclosed fluid is transmitted undiminished in all directions throughout the fluid and to the walls of its container.
-
E.
Stokes' law
Stokes' law is a fundamental equation in fluid dynamics that describes the drag force experienced by small spherical particles moving slowly through a viscous fluid.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
