1. What is Khosla's Formula?

Khosla's Formula is used to estimate rainfall depth based on runoff depth and temperature. It provides a method to calculate the vertical height of rainwater accumulated over a surface during a specific period.

2. How Does the Calculator Work?

The calculator uses Khosla's Formula:

\[ P_{cm} = R_{KC} + \frac{(T_f - 32)}{3.74} \]

Where:

\( P_{cm} \) — Rainfall Depth (cm)
\( R_{KC} \) — Runoff Depth in CM for Khosla's Formula (cm)
\( T_f \) — Temperature (°F)

Explanation: The formula calculates rainfall depth by adding the runoff depth to a temperature-dependent component derived from Fahrenheit temperature conversion.

3. Importance of Rainfall Depth Calculation

Details: Accurate rainfall depth estimation is crucial for hydrological studies, water resource management, irrigation planning, and flood prediction in various environmental and agricultural applications.

4. Using the Calculator

Tips: Enter runoff depth in centimeters and temperature in Fahrenheit. Ensure all values are valid (runoff depth ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the temperature component in the formula?
A: The temperature component adjusts for thermal effects on precipitation patterns and helps provide a more accurate estimation of rainfall depth.

Q2: What are typical values for rainfall depth?
A: Rainfall depth varies significantly by region and season, ranging from less than 1 cm in arid areas to over 50 cm in tropical regions during heavy rainfall events.

Q3: When should this formula be used?
A: Khosla's Formula is particularly useful in agricultural and hydrological applications where both runoff and temperature data are available for rainfall estimation.

Q4: Are there limitations to this formula?
A: The formula may be less accurate in extreme climatic conditions or regions with unusual temperature-precipitation relationships. Local calibration may be necessary for optimal results.

Q5: Can this formula be used for all types of precipitation?
A: The formula is primarily designed for liquid precipitation (rainfall) and may not accurately estimate solid precipitation (snow, hail) without additional adjustments.
