Rain water, also called precipitation, is a natural feature of the earth's weather system. Air currents in the atmosphere bring evaporated water from the ocean and the earth's surface up into the sky. The evaporated liquid condenses in the cold air, forming moisture-filled rain clouds.

Significance
Rain water's most well-known and most important effect is providing you with water to drink. According to the United States Geological Survey, rain water seeps into the ground in a process called infiltration. Some of the water seeps deep beneath ....etc

1. Alok and Bhanu play the following min-max game. Given the expression N=40+X+Y-Z, where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal st ....etc

Themal Comfort Presentation.
Sunrise and Sunset:
The yellow section shows when the sun is up, and how this changes over the year.
The sunrise and sunset times shown in the chart are approximate.
They are accurate for the latitude, and show the precise amount of daylight.
The charts are made assuming that the location is in the middle of an evenly spaced time zone.
For Lahore City, Pakistan, use latitude 31 33'N and longitude 074 20'E in the form. You'll need to know the time zone of the location.

DESIGN OF BOILER STACK
ABSTRACT
Chimney, which form the last component of a system using a flue gas such as feoiler, IC engines, play a vital role in maintaining efficiency, draft, etc, of a system and also in minimizing the atmospheric pollution.
The boiler plant of HOCL had used LSHS (low Sulphur heavy stock) as a fuel. Recently they changed the fuel to LSFO (low Sulphur furnace oil). As a combined effect of increased corrosion rate and natural calamities the stack had undergone failure. As per the Kerala State Polluti ....etc

LANDSCAPING FOR ENVIRONMENTAL PURPOSES


INTRODUCTION
Energy saving is possible with landscaping.

Although it is not possible to control temperature ,wind and other natural elements certain landscape particles can help modify the climate in and around the home.

By placing trees,shrubs,vines and landscape structures properly home owner reduce the energy required to keep homes comfortable during winter and summer.Along with the reduction of energy bills,a well planned landscape adds beauty,interest and in ....etc

groundwater recharge through wastewater ppt

Abstract :
Water that seeps into an aquifer is known as recharge. Recharge comes from a variety of sources, including seepage from rain and snow melt, streams, and groundwater flow from other areas. Recharge occurs where permeable soil allows water to seep into the ground. Areas in which this occurs are called recharge areas. They may be small or quite large. A small recharge area may supply all the water to a large aquifer. Streams that recharge groundwater are called losing streams because they lo ....etc

Water quality models are important tools used by the Maryland Department of the Environment (MDE) in developing Total Maximum Daily Loads (TMDLs), which serve as water quality standards. The MDE tool, which spatially interpolates output from the Chesapeake Bay Program Watershed Model (WSM), is often used because it requires little time, data, or training. In contrast, the WSM requires extensive time, data, and training to run. This study examines if the MDE tool provides accurate estimates of pollutant loads and whether the mid-level complexity ....etc
