Physics Of Water Running Off A Roof

The following approaches to redirect and capture runoff can be used to control heavy runoff causing prolonged wet areas or yard erosion.

Physics of water running off a roof.

You have to admit that whether you re in a drought situation or not it s hard to pass up that much of a free thing. A siphon is a way to carry water uphill without the use of pumps. Divide 100 by the number of downspouts in order to obtain the percentage of water collected from each downspout. Automatic overflow control directs water back to downspout when barrel is full.

If you have heavy runoff from roof downspouts and neighboring properties redirecting or capturing runoff can provide better control. A pocket of water gets trapped in the middle with nowhere to run and squirts out. A combination of gravity and atmospheric pressure drives the water through the hose even if parts of the hose. So a 50 x 20 roof is 600 x 240 multiply the roof dimensions by the number of inches of rainfall.

In case you are too afraid to watch it this dude jumps off the top of a building that is listed at 129 feet and lands in water. The drainage system of any roof can be located at the edge or in the middle of the roof. For a large roof it is recommended to have drains placed at multiple locations within the area of the roof. If you are afraid of heights this is a super scary video.

It consists of a hose full of water with one end in a water source and the other end pouring out into a destination that is below the source. Determine the percentage of water collected from each downspout p. The surprisingly strange physics of water. Count the number of downspouts coming from your roof.

In this example 600 x 240 x 1 144 000 cubic inches of water divide by 231 to get the number of gallons because 1 gallon 231 cubic inches. How water runs off a roof depends on the amount of rainfall and how quickly it needs to drain. Convert the percentage to a decimal by dividing the percentage by 100. Why water means trouble when the ground around the foundation is repeatedly soaked from water that drains off the roof it creates problems both inside and outside of your home.

If you get about 10 inches of rain over the course of the spring and summer an average 1 360 square foot roof would yield 8 160 gallons of rainwater. If you can get in the attic and look you should be able to see where the water stained. Take the dimensions of the footprint of your roof and convert them to inches. More than like the water is leaking from a nail that popped up from the temperature changes over the years.
