Pascal’s Principle

Transmitting Pressure in a Fluid In the 1600s, Blaise Pascal developed a principle to explain how pressure is transmitted in a fluid Fluid exerts pressure on any surface it touches.

Pascal’s Principle Pascal’s principle states that pressure increases by the same amount throughout an enclosed or confined fluid When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid.
