How do you calculate rainfall in Litres
We use the following formula to calculate the amount of collected rainwater: mean annual rainfall in mm x area in m2 x runoff factor = 48 600 litres in our example.
How rainfall is measured in cm
The gauges 5 inch (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) (127 mm) diameter sharp brass or steel rim
How do you calculate rainfall per hour
Calculating Precipitation Rate 60 minutes per hour divided by 7.48 gallons per cubic foot times 12 inches per foot gives 96.25 = constant that converts gallons per minute (GPM) to inches per hour.
How do you calculate annual rainfall in mm
The total annual rainfall is equal to the sum of the precipitation in all twelve months, which equals 128.7 cm. (i) Annual rainfall is therefore equal to the total of the precipitation in all twelve months.
How do you calculate cumulative rainfall
The cumulative excess rainfall (Pe) will be equal to P – Ia – Fa once Ia and Fa have been calculated for each time step. In this case, Ia = total rainfall. Once total rainfall exceeds Ia, then Fa will be calculated for each time step.
What is the Thiessen polygon method
Perpendicular bisectors are constructed to the lines connecting each measuring station with those immediately surrounding it. These bisectors form a series of polygons, each polygon containing one station. This method assigns areal significance to point rainfall values.
How many litres is 1mm of rain
One litre of water is produced by one millimeter of rainfall for every square meter of horizontal surface area.
What is the formula for calculating rainfall
Determine the area at the top of the bucket (this is the area over which the rain is collected) and divide the rainfall volume by this area to obtain the average volume of rain (16 September 2013).
What does 40mm of rain mean
A light shower is less than 2 mm per hour, a moderate shower is greater than 2 mm but less than 10 mm per hour, and a heavy shower is greater than 10 mm but less than 50 mm per hour. Heavy rain is greater than 4 mm per hour but less than 8 mm per hour, and very heavy rain is greater than 8 mm per hour.
How much is 1mm rain
One millimeter of rain equals one litre of water in a square meter, or 140 millimeters of rain can fill a typical cricket stadium with 23.8 lakh litres of water!
How much is 10 mm of rain in a day
Youve got your decimal point wrong; 1mm over 1 sq m is a litre, 10 mm gives 10 litres; roughly equivalent to 0.8 inches of rain in 24 hours.20 Jun 2007
How do you calculate rainfall on a roof
This capacity can be calculated using the following equation: Annual rainfall (in millimeters) x Roof surface area (in square meters) = Roof catchment capacity. Roughly speaking, 1 millimeter of rain over 1 square metre of roof equals 1 litre of water.
How many Litres is a square meter

1 liter = | 0.01 m2 | 1000 liter |
---|---|---|
2 liter = | 0.0159 m2 | 2828.4271 liter |
3 liter = | 0.0208 m2 | 5196.1524 liter |
4 liter = | 0.0252 m2 | 8000 liter |
5 liter = | 0.0292 m2 | 11180.3399 liter |
Is 20 40mm of rain a lot
On the other hand, when the range of rainfall is between 15 and 20 mm but the totals are reasonably large, widespread rain is typically falling from a broad-scale cloud system rather than isolated showers or thunderstorms.
How do you calculate rainfall per square meter
One millimeter of rain falling on one square meter of roof will provide you with roughly one litre of water in your tank, according to a straightforward calculation you can use to estimate the amount of rainfall you can expect to harvest from your roof.

How much water is in an inch of rain
An inch of snow falling evenly on an acre of ground is equal to about 2,715 gallons of water, while an inch of rain weighs about 113 tons and is equal to 27,154 gallons of water.
Is 1 inch of rain in 24 hours a lot
One (1.00) inch of rain would result in deep standing water for extended periods of time; light to moderate rain that does not reach this level would never last for more than two to five hours.
