What is Pressure?

Pressure is defined as the force applied per unit area. Mathematically, it is expressed as:

P=FAP = \frac{F}{A}P=AF​

Where:

• $P$ = Pressure

• $F$ = Force applied

• $A$ = Area over which the force is distributed

Pressure is measured in various units, including Pascal (Pa), PSI (pounds per square inch), Bar, and atmospheres (atm). Understanding these units and converting between them is crucial for accuracy in engineering, construction, and scientific research.

Types of Pressure Calculators

1. Fluid Pressure Calculator

A fluid pressure calculator measures the pressure exerted by liquids in a system. It is widely used in hydraulics, plumbing, and water supply systems.
Example: Calculating water pressure in a storage tank.

2. Gas Pressure Calculator

Gases behave differently from liquids. A gas pressure calculator uses laws such as Boyle’s Law and Charles’s Law to determine the pressure of gases under various conditions.

3. Atmospheric Pressure Calculator

Atmospheric pressure changes with altitude and weather conditions. An atmospheric pressure calculator is essential for aviation, meteorology, and environmental studies.

4. Hydraulic Pressure Calculator

Hydraulic machines rely on fluid force. The hydraulic pressure calculator helps engineers design systems efficiently, ensuring optimal force transmission.
