## About Rain Angle Calculator (Formula)

The Rain Angle Calculator is a tool used to estimate the angle at which rainwater falls from the sky. This calculator helps determine the inclination or slope of rainfall based on the direction and speed of raindrops.

The formula for calculating the rain angle depends on the horizontal velocity and vertical velocity components of raindrops. In a simplified scenario, assuming vertical free fall and neglecting air resistance, the formula can be expressed as:

Rain Angle = arctan(Vertical Velocity / Horizontal Velocity)

Where: Rain Angle = Angle at which rainwater falls Vertical Velocity = Speed of raindrops in the vertical direction Horizontal Velocity = Speed of raindrops in the horizontal direction

To use this formula, you need to know the vertical and horizontal velocities of raindrops. Take the arctan of the ratio of vertical velocity to horizontal velocity to obtain the rain angle.

It’s important to note that the rain angle calculated by this formula assumes ideal conditions and neglects factors like wind, air resistance, and droplet size variations. In reality, rain angles can vary due to these factors and the specific atmospheric conditions.

When using the Rain Angle Calculator, ensure accurate measurement or estimation of the vertical and horizontal velocities to obtain reliable results. Additionally, consider any specific adjustments or corrections needed for different rainfall scenarios or meteorological conditions.

By applying the rain angle formula correctly, you can estimate the angle at which rainwater falls, aiding in the understanding of rainfall patterns, hydrological analysis, and various meteorological applications.
