1. What is Average Horizontal Velocity at a Node?

Average Horizontal Velocity at a Node refers to the average velocity of the fluid flow in the horizontal direction (typically x-direction or east-west direction) at that particular node in wave dynamics and harbor oscillation studies.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V' = \frac{H_w \times \lambda}{\pi \times d \times T_n} \]

Where:

\( V' \) — Average Horizontal Velocity at a Node (m/s)
\( H_w \) — Standing Wave Height of Ocean (m)
\( \lambda \) — Wavelength (m)
\( \pi \) — Archimedes' constant (≈3.14159)
\( d \) — Water Depth at Harbor (m)
\( T_n \) — Natural Free Oscillating Period of a Basin (s)

Explanation: This formula calculates the average horizontal velocity at a node based on wave characteristics and basin properties.

3. Importance of Velocity Calculation

Details: Calculating average horizontal velocity at nodes is crucial for understanding wave dynamics, harbor resonance effects, and designing coastal structures that can withstand wave-induced forces.

4. Using the Calculator

Tips: Enter all values in appropriate units (meters for length, seconds for time). All values must be positive and greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a standing wave in oceanography?
A: A standing wave results when two equal waves are moving in opposite directions, creating stationary points called nodes and antinodes.

Q2: How does water depth affect horizontal velocity?
A: Shallower water depths generally result in higher horizontal velocities for the same wave characteristics due to wave shoaling effects.

Q3: What is the natural oscillating period of a basin?
A: It's the time it takes for a wave to travel from one end of the basin to the other and back again, representing the basin's resonant period.

Q4: Why is this calculation important for harbor design?
A: Understanding velocity patterns helps design harbors that minimize wave-induced motions and ensure safe navigation and mooring conditions.

Q5: Are there limitations to this formula?
A: This formula provides an average estimation and may not capture complex interactions in irregular basin geometries or under extreme wave conditions.
