1. What is Deepwater Celerity?

Deepwater celerity refers to the speed at which a wave propagates through deep water. It is measured in feet per second (FPS) and is an important parameter in oceanography and coastal engineering.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Wave\ Period \) — Time between successive wave peaks or troughs (seconds)
• 5.12 — Constant conversion factor for deep water waves

Explanation: This formula provides the wave propagation speed in feet per second based on the wave period measurement.

3. Importance of Celerity Calculation

Details: Calculating wave celerity is crucial for understanding wave behavior, predicting wave arrival times, and designing coastal structures that can withstand wave forces.

4. Using the Calculator

Tips: Enter the wave period in seconds. The value must be greater than zero. The calculator will provide the celerity in feet per second.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between deepwater and shallow water celerity?
A: Deepwater celerity depends only on wave period, while shallow water celerity also depends on water depth due to bottom friction effects.

Q2: What are typical values for wave celerity?
A: Typical deepwater wave celerity ranges from 10-50 ft/s depending on wave period, with longer period waves traveling faster.

Q3: How is wave period measured?
A: Wave period is typically measured as the average time between successive wave crests passing a fixed point, usually using wave buoys or sensors.

Q4: Why is the constant 5.12 used in this formula?
A: The constant 5.12 comes from the conversion of the deepwater wave celerity formula \( C = gT/(2\pi) \) to feet and seconds units.

Q5: Can this formula be used for all water depths?
A: No, this formula is specifically for deep water conditions where water depth is greater than half the wavelength. Different formulas apply for intermediate and shallow water.
