1. What is Hydrostatic Pressure?

Hydrostatic pressure refers to the pressure that any fluid in a confined space exerts. If fluid is in a container, there will be some pressure on the wall of that container. It is the pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity.

2. How Does the Calculator Work?

The calculator uses the hydrostatic pressure formula:

\[ p_{hydrostatic} = 10 \times \rho \times (H - 0.3) \]

Where:

\( p_{hydrostatic} \) — Hydrostatic pressure (N/mm²)
\( \rho \) — Density of liquid stored (kg/m³)
\( H \) — Height of tank (meters)

Explanation: The formula calculates the pressure at the bottom of a tank, accounting for the density of the liquid and the height of the liquid column, with a standard 0.3 meter adjustment factor.

3. Importance of Hydrostatic Pressure Calculation

Details: Accurate hydrostatic pressure calculation is crucial for tank design, structural integrity assessment, safety evaluations, and determining appropriate wall thickness for liquid storage containers.

4. Using the Calculator

Tips: Enter liquid density in kg/m³ and tank height in meters. All values must be valid (density > 0, height > 0). The calculator will compute the hydrostatic pressure at the bottom of the tank.

5. Frequently Asked Questions (FAQ)

Q1: Why is there a 0.3 meter subtraction in the formula?
A: The 0.3 meter adjustment accounts for typical installation factors and provides a safety margin in pressure calculations.

Q2: What units should be used for input values?
A: Density should be in kg/m³ and height in meters for accurate results in N/mm².

Q3: Does this formula work for all types of liquids?
A: Yes, the formula works for any liquid as long as the correct density value is provided.

Q4: How does temperature affect the calculation?
A: Temperature affects liquid density. For accurate results, use the density value at the operating temperature.

Q5: Is this pressure calculation applicable to pressurized tanks?
A: This formula calculates only the hydrostatic pressure component. For pressurized tanks, additional pressure must be added to the hydrostatic pressure.
