1. What is the Pressure at Any Points in Liquid Formula?

The formula calculates absolute pressure at any point in a liquid, accounting for both atmospheric pressure and the pressure due to the liquid column above the point. It provides the total pressure experienced at a specific depth in a fluid.

2. How Does the Calculator Work?

The calculator uses the pressure formula:

\[ P_{ab,H} = P_{atm} + \gamma \cdot h \]

Where:

\( P_{ab,H} \) — Absolute pressure for both direction (Pascal)
\( P_{atm} \) — Atmospheric pressure (Pascal)
\( \gamma \) — Specific weight of liquid (N/m³)
\( h \) — Height of crack/depth (Meter)

Explanation: The formula combines atmospheric pressure with the hydrostatic pressure created by the weight of the liquid column above the measurement point.

3. Importance of Pressure Calculation

Details: Accurate pressure calculation is crucial for fluid mechanics, hydraulic systems, structural engineering, and understanding fluid behavior in various containers and environments.

4. Using the Calculator

Tips: Enter atmospheric pressure in Pascal, specific weight of liquid in N/m³, and height/depth in meters. All values must be valid non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between absolute and gauge pressure?
A: Absolute pressure includes atmospheric pressure, while gauge pressure measures pressure relative to atmospheric pressure (absolute pressure minus atmospheric pressure).

Q2: Why is specific weight used instead of density?
A: Specific weight (weight per unit volume) incorporates gravity, making it more convenient for pressure calculations in gravitational fields.

Q3: Does this formula work for all liquids?
A: Yes, the formula works for any incompressible fluid, but the specific weight value must be appropriate for the particular liquid being measured.

Q4: How does temperature affect the calculation?
A: Temperature affects the specific weight of liquids. Warmer temperatures generally decrease specific weight due to thermal expansion.

Q5: What are typical specific weight values for common liquids?
A: Water at 4°C: 9810 N/m³, Mercury: 133,100 N/m³, Oil: typically 7000-9000 N/m³ depending on type.
