GPM to Precipitation Rate Calculator

Calculate Precipitation Rate



Formula

The formula to calculate the precipitation rate (PR) is:

\[ PR = \frac{\text{GPM} \times 96.3}{A} \]

What is Precipitation Rate?

Precipitation rate is a measure of how quickly water is being applied to a given area, typically in inches per hour (in/hr). It is often used in irrigation and landscaping to ensure that water is distributed evenly across a specified area. This calculation helps in understanding the efficiency of water usage and in planning irrigation systems to maintain proper soil moisture levels.

Example Calculation

Consider an example where:

Using the formula to calculate the Precipitation Rate:

\[ PR = \frac{10 \times 96.3}{500} = 1.93 \]

This means that the precipitation rate is approximately 1.93 inches per hour.
