Pascal’s law || class-11th||physics || Fluid mechanics .
Statement of Pascal’s Law Pascal’s Law states that any pressure applied to a confined, incompressible fluid is transmitted undiminished throughout the fluid in all directions and acts with equal force on equal areas. Alternatively, in the absence of gravity, the pressure at any point in a fluid at rest is the same in all directions.…

A liquid at rest exerts force perpendicular to the surface of the container at every point.
Show that a liquid at rest exerts force perpendicular to the surface of the container at every point. Proof: Suppose the force exerted by the liquid on the container’s surface acts at an angle to the perpendicular (normal) to the surface. We can resolve this force into two components: The tangential component would cause the…

streamline, turbulent and laminar flow.
What is streamline flow ? Streamline flow— When liquid flows such that each particle of the liquid passing a given point moves along the such path and has the same velocity as its predecessor, the flow is called streamline flow or steady flow. 1. What is Streamline Flow? Streamline flow, also called laminar flow, is…
