The fluid must be a liquid (not a gas)

To meet Pascal's principle, the following conditions must be satisfied:

1. The fluid must be incompressible: This means that the fluid does not significantly change in volume when subjected to pressure. Liquids, such as water or oil, are commonly used in applications involving Pascal's principle.

2. The fluid must be pure and homogeneous: Impurities or variations in the composition of the fluid can affect its behavior and make it difficult to apply Pascal's principle accurately. Therefore, it is important to ensure that the fluid used is free from contaminants and has uniform properties throughout.

3. The hydraulic pistons must have a volume: Hydraulic pistons are used to transmit the pressure from one point to another in a hydraulic system. The pistons create a pressure difference that causes the fluid to move and transmit force. It is essential that the pistons have a volume to displace the fluid and apply the principle effectively.

4. The walls of the container enclosing the fluid must be airtight: To maintain the pressure and prevent any leakage or loss of fluid, the container holding the fluid must have airtight walls. This ensures that the pressure created by the application of force remains constant and is effectively transmitted through the system.

5. The output piston must be larger than the input piston: Pascal's principle relies on the fact that pressure is transmitted equally in all directions in an enclosed fluid. This means that the area of the output piston must be larger than the input piston to achieve a mechanical advantage. By increasing the area, a smaller force applied to the input piston can generate a larger force at the output piston.

By meeting these conditions, Pascal's principle can be effectively applied to hydraulic systems, enabling the transmission of force and pressure throughout the system.
