Pascal's Law

Pascal's Law

Pressure applied to an enclosed fluid is transmitted equally in all directions.

### Formula

$$P_1=P_2$$

### Hydraulic Lift Relation

$$\frac{F_1}{A_1}=\frac{F_2}{A_2}$$

### Terminologies

- F₁, F₂ → Forces on pistons.

- A₁, A₂ → Areas of pistons.

### Conditions / Special Cases

Fluid must be enclosed.

### Usage

- Used in hydraulic machines.
