How do you convert mm of rain to liters?
In terms of volume, with a rainfall of 10 mm, every square metre of the field receives 0.01 m, or 10 litres, of rain water. With a rainfall of 1 mm, every square metre receives 1 litre of rain water. A rainfall of 1 mm supplies 0.001 m3, or 1 litre of water to each square metre of the field.
How do you calculate the volume of water in rainfall?
Formula: Area (Length x Width) x Rainfall
- A = Length of the roof area.
- B = Width of the roof area.
- C= The amount of rainfall in inches.
- The formula is A x B x C = Water Volume.
How is irrigation depth calculated?
Finally, the depth of water applied can be calculated by multiplying the application rate by the duration of irrigation. Continuing the previous example, for an application rate of 0.25 in/hr and a 6 hr irrigation duration, the gross depth of water applied would be 1.5 inches (D = 0.25 in/hr x 6 hr=1.5 inches).
How much is 80 mm of rain in inches?
Inches to Millimetres Conversion Table – 1 to 200 inches
| Inches (in) | Millimetres (mm) |
|---|---|
| 80 | 2032 |
| 81 | 2057.4 |
| 82 | 2082.8 |
| 83 | 2108.2 |
How much is a Metre of rain?
In an area of 1 square metre, 1 m of rain will mean 1000 litres. Since 1 m equals 1000 mm, 1 mm of rain is 1 litre per square metre. Notice that 1 litre is 0,001 cubic metres, this means “1 litre per square metre” can be written as 0.001 m^3 / 1 m^2, which can be simplified to 0.001 m, which is 1 mm.
What does 100 mm rainfall mean?
One millimeter of rainfall is the equivalent of one liter of water per square meter. The standard way of measuring rainfall or snowfall is the standard rain gauge, which can be found in 100-mm (4-in) plastic and 200-mm (8-in) metal varieties.
How the rainfall is measured in mm?
Instruments. The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.
How do you calculate annual rainfall volume?
If you normally measure annual rainfall in inches, simply divide inches of rain by 12 to get annual rainfall in feet. For example, folks in Phoenix, Arizona get about 7 inches of annual rainfall, so they would divide 7 by 12 to get 0.58 foot of annual rain.
How do I calculate water to irrigation?
To calculate the amount of water you use, multiply the width times the length of your yard in feet to get the number of square feet of area. Then multiply that figure by 0.623 to come up with the number of gallons used (or use our calculator below). This assumes that your yard is square or rectangular.
What is water depth measured in?
fathoms
Water depths are measured by soundings usually acquired by hydrographic surveys. The depths may be in either feet or fathoms (the chart will indicate which). A fathom is a nautical unit of measurement and is equal to six feet .
How much does 20 quarts of soil weigh in cubic feet?
A 20 dry quarts package of potting soil is approximately 3/4 of a cubic foot. Furthermore, how much does a bag of soil weigh? A cubic foot of soil weighs between 74 and 110 pounds, depending on the type of soil and how moist it is.
What is the volumetric water content of soil?
The volumetric water content is the ratio of the volume of water to the unit volume of soil. Volumetric water content can be expressed as ratio, percentage or depth of water per depth of soil (assuming a unit surface area), such as inches of water per foot of soil.
What is the degree of saturation in a soil sample?
A soil sample has a void ratio of 0.8, degree of saturation of 0.9 and Gs of 2.68. Using SI units compute, total unit weight, dry unit weight, water content, and saturated unit weight.
Why does clay soil have a higher water table than sandy?
The rise in water table for each inch of rain is much greater for a clay soil than for a sandy soil. That is because a clay soil has a much larger percentage of fine pores that hold water against drainage so at FC there is not as much room left for more water.
