What is Rate precipitation?
Precipitation rate means the amount of water in inches (P.R.) that an irrigation system discharges, usually measured in inches per hour. Precipitation rate means the rate at which water is applied per unit of time, usually measured in inches per hour.
How do you calculate precipitation rate?
Precipitation rate (PR) is a calculation of the flow rate (application rate) over the square footage of the zone. 96.25 = constant that converts gallons per minute (GPM) to inches per hour. It is derived from 60 minutes per hour divided by 7.48 gallons per cubic foot, times 12 inches per foot.
How do you calculate rainfall precipitation?
To convert this to gallons per hour we need to multiply by 60 minutes. To work this into the constant, we multiply 1.604 in x 60 min and we come up with the 96.3 for the formula….Irrigation Design Tip: Calculating Precipitation Rates.
| US Measurements | Metric |

| PR = the average precipitation rate in inches per hour | PR = the average precipitation rate in millimeters per hour |
What is a low precipitation rate?
Precipitation or application rate (these terms are often interchange able) is simply the rate at which sprinklers deliver water to a target area. Chip Kah, president of K-Rain, in Riviera Beach, Florida, says that “anything under one-half inch per hour, 0.5 and below, we would consider a low precipitation rate.”
What is rain also called?
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzling, rain, sleet, snow, ice pellets, graupel and hail.
What is precipitation rate in irrigation?
Precipitation rate is the speed at which water is being applied to a specific area. To accomplish this, examine the amount of water falling into each individual area from all sprinklers supplying that area.
How many inches is a sprinkler per hour?
For conventional sprayheads, precipitation rates typically range from 1.3 inches to 2 inches per hour. For gear drive rotors, precipitation rates typically range from 0.4 inch to 1 inch per hour. For rotary nozzles, precipitation rates typically range from 0.4 inch to 0.6 inch per hour.
Is 1 to 2 inches of rain a lot?
1/2 (0.5) of an inch of rain – A light rain never reaches this amount, moderate rain for 1-2 hours or heavy rain for 30-45 minutes. One (1.00) inch of rain – A light moderate rain never reaches this amount, heavy rain for several hours (2-5 hours). There would be deep standing water for long periods of time.
Is 1mm a lot of rain?
Slight rain: Less than 0.5 mm per hour. Moderate rain: Greater than 0.5 mm per hour, but less than 4.0 mm per hour. Moderate shower: Greater than 2 mm, but less than 10 mm per hour. Heavy shower: Greater than 10 mm per hour, but less than 50 mm per hour.
What is precipitation in simple words?
Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow.
What are the 3 types of precipitation?
The most common types of precipitation are rain, hail, and snow.
What do you call a weak rain?
We use the words “drizzling” or “sprinkling” here. They both mean “to rain or let fall in fine drops” If it’s very, very light rain, you can use the word “mist”. “Drizzling” usually implies a little harder rain than “sprinkling”.
How do I calculate my precipitation rate?
How to calculate precipitation rate The Measuring Can Method. This is as simple as measuring rainfall. Take a rain gauge, or non tapered cup or can, set it… Using the Precipitation Rate Formula. In this example, we are using what is called the Total Area Method. This… Example:. An area, with a
What is the annual precipitation in Antarctica?
The average annual precipitation of the continent of Antarctica is about 166 mm. Thus, this fact makes Antarctica a true desert as per the classification by Peveril Meigs .
