CALCULATE RAINFALL FOR HARVESTING

How to Calculate Rainfall for Harvesting
Step
1
The first thing to do is to figure the area of the structure. Begin by using the measuring tape, and measure your roof from one eave to the next. You can do this on the ground because it doesn’t matter whether your roof is flat or sloped. So let’s say the measurement is 30 feet X 50 feet. Write this down.
Step
2
You now have the measurements necessary to find the square footage of your roof.Multiply 30 feet times 50 feet. That’s 1,500 square feet. And that is your catchment area. Write that down. Area = length (feet) X width (feet).
Step
3
Now, check the rain gauge. For simplicity, let’s say that it rained one inch. Write down the number of inches.
Step
4
An inch of rainfall on a square foot of surface area yields .623 gallons.
Step
5
Now, multiply .623 gallons by the number of surface square feet. In this case it would be 30 feet X 50 feet= 1,500 square feet X 1 inch X .623 gallons per square foot per inch of rainfall. That comes to 9.345 gallons per square feet.
Step
6
Let’s say instead it rained 2.5 inches. Then the calculation would read 30 feet X 50 feet=1,500 square feet X 2.5 inches X .623 gallons per square foot per inch of rainfall.The total number of gallons here is 2,336.25 inches of rainfall.

RICHTAR MAGNITUDE

The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the variation in the distance between the various seismographs and the epicenter of the earthquake). The original formula is:[4]

where A is the maximum excursion of the Wood-Anderson seismograph, the empirical function A0 depends only on the epicentral distance of the station, δ. In practice, readings from all observing stations are averaged after adjustment with station-specific corrections to obtain the ML value.
Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to a doubling of the energy released.
Events with magnitudes of about 4.6 or greater are strong enough to be recorded by any of the seismographs in the world, given that the seismograph's sensors are not located in an earthquake's shadow.
The following describes the typical effects of earthquakes of various magnitudes near the epicenter. This table should be taken with extreme caution, since intensity and thus ground effects depend not only on the magnitude, but also on the distance to the epicenter, the depth of the earthquake's focus beneath the epicenter, and geological conditions (certain terrains can amplify seismic signals).

WHAT IS LATITUDE AND LONGITUDE

We can imagine the Earth as a sphere, with an axis around which it spins. The ends of the axis are the North and South Poles. The Equator is a line around the earth, an equal distance from both poles. The Equator is also the latitude line given the value of 0 degrees. This means it is the starting point for measuring latitude. Latitude values indicate the angular distance between the Equator and points north or south of it on the surface of the Earth.


A line connecting all the points with the same latitude value is called a line of latitude. This term is usually used to refer to the lines that represent values in whole degrees. All lines of latitude are parallel to the Equator, and they are sometimes also referred to as parallels. Parallels are equally spaced. There are 90 degrees of latitude going north from the Equator, and the North Pole is at 90 degrees N. There are 90 degrees to the south of the Equator, and the South Pole is at 90 degrees S. When the directional designators are omitted, northern latitudes are given positive values and southern latitudes are given negative values.

What is longitude?

Prime Meridian
Lines of longitude, called meridians, run perpendicular to lines of latitude, and all pass through both poles. Each longitude line is part of a great circle. There is no obvious 0-degree point for longitude, as there is for latitude. Throughout history many different starting points have been used to measure longitude. By international agreement, the meridian line through Greenwich, England, is currently given the value of 0 degrees of longitude; this meridian is referred to as the Prime Meridian. Longitude values are indicate the angular distance between the Prime Meridian and points east or west of it on the surface of the Earth.


The Earth is divided equally into 360 degrees of longitude. There are 180 degrees of longitude to the east of the Prime Meridian; when the directional designator is omitted these longitudes are given positive values. There are also 180 degrees of longitude to the west of the Prime Meridian; when the directional designator is omitted these longitudes are given negative values. The 180-degree longitude line is opposite the Prime Meridian on the globe, and is the same going either east or west.
