How does Bernaulli's equation and Pascal law work in hydraulic jack?

Question

Accepted Answer

Bernaulli's equation and Pascal's law work together in a hydraulic jack to lift heavy objects by applying pressure through a fluid.

Bernaulli's equation states that an increase in fluid speed results in a decrease in pressure, allowing the hydraulic jack to lift heavy objects by applying pressure through a fluid.
Pascal's law states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and the walls of its container, enabling the hydraulic jack to exert a large force with a small input force.
The hydraulic jack uses a small input force on a small piston to create a high pressure in the fluid, which is transmitted through the fluid to a larger piston that exerts a much larger force to lift heavy objects.
For example, when a small force is applied to the small piston of a hydraulic jack, it creates a high pressure in the fluid. This pressure is transmitted through the fluid to the larger piston, which then exerts a much larger force to lift a heavy object.
