Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Pascal's Law (Hydraulics) is an essential tool for understanding Pascal's Law (Hydraulics) in quantitative terms. Calculate F2 given F1, A1, A2 (F1/A1 = F2/A2).

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = (f1 ÷ a1) × a2
Eq 1.1: Governing Formula

Symbol Parameter Unit
f1 Input Force N
a1 Input Area
a2 Output Area

Practical Calculation Example

Problem

Calculating the result when:

  • Input Force = 100 N
  • Input Area = 25
  • Output Area = 95

Solution

Substituting into Eq 1.1:

Result = (100 ÷ 25) × 95
