1. What is Water Pressure at Depth?

Definition: This calculator determines the water pressure at a specific depth using the hydrostatic pressure formula.

Purpose: It helps understand the immense pressure at Titanic's depth (3810 meters) and can be adapted for other underwater calculations.

2. How Does the Calculator Work?

The calculator uses the hydrostatic pressure formula:

Where:

• \( P \) — Water pressure (Pascals)
• \( \rho \) — Water density (typically 1025 kg/m³ for seawater)
• \( g \) — Gravitational acceleration (9.81 m/s²)
• \( d \) — Depth below surface (meters)

Explanation: Pressure increases linearly with depth due to the weight of the water column above.

3. Importance of Pressure Calculation

Details: Understanding underwater pressure is crucial for submarine design, deep-sea exploration, and understanding the conditions at Titanic's wreck site.

4. Using the Calculator

Tips: Default values are set for Titanic's depth (3810m) with seawater density (1025 kg/m³). You can adjust any parameter.

5. Frequently Asked Questions (FAQ)

Q1: How much pressure was at Titanic's depth?
A: Approximately 38,200 kPa (or about 381 atmospheres) using default values.

Q2: Why is seawater density 1025 kg/m³?
A: Seawater is denser than pure water due to dissolved salts (average salinity 3.5%).

Q3: Does temperature affect the calculation?
A: Yes, but minimally. Warmer water is slightly less dense (about 2% difference 0-30°C).

Q4: How does this compare to atmospheric pressure?
A: Every 10 meters of seawater equals ~1 atmosphere, so Titanic's depth equals ~381 atmospheres.

Q5: What's the pressure in other units?
A: 1 MPa = 10 bar = 145 psi. At Titanic's depth: ~38.2 MPa or 5,540 psi.
