Physics of water running off a roof.

If you are afraid of heights this is a super scary video. Convert the percentage to a decimal by dividing the percentage by 100. Automatic overflow control directs water back to downspout when barrel is full. 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.

So a 50 x 20 roof is 600 x 240 multiply the roof dimensions by the number of inches of rainfall. More than like the water is leaking from a nail that popped up from the temperature changes over the years. If you have heavy runoff from roof downspouts and neighboring properties redirecting or capturing runoff can provide better control. Determine the percentage of water collected from each downspout p.

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. If you can get in the attic and look you should be able to see where the water stained. Divide 100 by the number of downspouts in order to obtain the percentage of water collected from each downspout. Take the dimensions of the footprint of your roof and convert them to inches.

A combination of gravity and atmospheric pressure drives the water through the hose even if parts of the hose. The surprisingly strange physics of water. 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. 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.

The following approaches to redirect and capture runoff can be used to control heavy runoff causing prolonged wet areas or yard erosion. A siphon is a way to carry water uphill without the use of pumps. A pocket of water gets trapped in the middle with nowhere to run and squirts out. For a large roof it is recommended to have drains placed at multiple locations within the area of the roof.

These techniques will minimize the amount of water that accumulates or that causes erosion in the problem area. Count the number of downspouts coming from your 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. How water runs off a roof depends on the amount of rainfall and how quickly it needs to drain.
