1. What is the Distance Travelled Formula?

The distance travelled formula calculates the distance covered by an object moving at a constant velocity over a specific time period. It is a fundamental equation in physics and fluid dynamics.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Distance Travelled (meters)
• \( v_s \) — Surface Velocity of River (m/s)
• \( t \) — Time Taken to Travel (seconds)

Explanation: This formula multiplies the surface velocity by the time taken to determine the total distance covered.

3. Importance of Distance Calculation

Details: Accurate distance calculation is crucial for hydrological studies, flood prediction, sediment transport analysis, and environmental monitoring of river systems.

4. Using the Calculator

Tips: Enter surface velocity in m/s and time in seconds. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is surface velocity of a river?
A: Surface velocity refers to the speed of water flow at the surface of the river, which can be measured using floats or current meters.

Q2: Does this formula account for varying velocity?
A: No, this formula assumes constant velocity. For varying velocities, integration methods would be required.

Q3: How accurate is surface velocity measurement?
A: Surface velocity measurements provide a rough estimate of runoff and may differ from average cross-sectional velocity due to wind and other factors.

Q4: What units should be used?
A: For consistent results, use meters per second for velocity and seconds for time to get distance in meters.

Q5: Can this be used for other fluids besides water?
A: Yes, the formula applies to any fluid motion where surface velocity can be measured and time is known.
