12" x 12" x 1"= 144 cubic inches, which is equal to .623 gallons therefore a one thousand square foot roof receiving one inch of rain will catch 623 gallons.
The idea is to divide the number of inches of rain by the number of hours. That will give you the unit rain, in inches per hour.
Grammatically, "Does the rain" is correct. Rain may represent many individual rain drops, which is why "Do rain drops" would be correct, however rain represents it as a whole, so "Does the rain" is the appropriate form.
The proper slope for newly installed gutters is 1/4 inch of slope for every 10 feet of gutter. This slope keeps water from standing after a heavy rain.
It is singular. "The rain is falling." To be plural, the usage would be something like "the rain drops are." (rain would be an adjective)
25 litres per square metre
75mm of rain is equivalent to 75 liters of water per square meter.
1 litre.
One millimeter of rain is equivalent to one liter of water per square meter. This means that if one millimeter of rain falls over an area of one square meter, it would fill up a volume of one liter.
1 litre will be collected per square meter of surface area from one millimeter of rain
12" x 12" x 1"= 144 cubic inches, which is equal to .623 gallons therefore a one thousand square foot roof receiving one inch of rain will catch 623 gallons.
An inch of rain implies water one inch deep per surface area. An inch of rain equals 5.61 gallons per yard. An inch of rain equals 27,150 gallons per acre.
one inch of rain over one square mile equals 17.4 millions pounds (about 72,000 tons)
Rainfall is typically measured using a rain gauge, which collects and measures the amount of rainwater that falls over a specific area of land, usually per square meter. The collected water is then measured in millimeters or inches to determine the amount of rainfall.
The amount of time it will take for one inch of rain to fall will vary. One inch of rain can fall in as little as 15 minutes in heavy downpour. It could also take up to several hours. It is mainly based upon the intensity of rainfall.
