Soil Suitability for Geothermal Heat Pumps (Closed-Loop Horizontal Residential)

Ground source heat pump systems provide a viable alternative to conventional heating and cooling systems in the move towards sustainable building solutions. The most important factor for successful operation of a ground loop heat system is the rate of heat transfer between the pipe and surrounding soil.

Chain Survey Steps - Method for Performing Chain Surveying

Chain survey is the simplest method of surveying. In this survey only measurements are taken in the field, and the rest work, such as plotting calculation etc. are done in the office. This is most suitable adapted to small plane areas with very few details. If carefully done, it gives quite accurate results. The necessary requirements for field work are chain, tape, ranging rod, arrows and sometime cross staff.

What is Environmental Impact Assessment and its Objectives

An environment impact Assessment is an event or effect, which results from a prior event. It can be described as the change in an environmental parameter, over a specific period and within a defined area, resulting from a particular activity compared with the situation which would have occurred had the activity not been initiated.

Chrystaller Central Place Theory

Chrystaller Central Place Theory: Theory was first proposed in the 1930s by German geographer Walter Chrystaller, based on his studies of southern Germany. August Losch in Germany and Brian Berry and others in the U.S further developed concepts during the 1950s. The theory applies most clearly in regions such as the Great Plains, which are neither heavily

Important Definitions in Airport Engineering

It involves the design and construction of facilities for the landing, take off, movement of aircraft on the ground, parking of aeroplanes on loading aprons, maintenance and repairs of areas, access roads from the city side to airport, and handling of passengers, baggage and freight. Aviation means flying with the aid of a machine, heaver than air.

Prestressed Concrete - Definition and Methods of Pre-Stressing

In this method, the prestressing tendons are initially tensioned between fixed abutments and anchored. With the formwork in place, the concrete is cast around the highly stressed steel tendons and cured. When the concrete has reached its required strength, the wires are cut or otherwise released from the abutments. As the highly stressed steel attempts

Definitions of Technical Terms in Hydraulic Structures

When the angle between the headwork axis and the river axis exceeds 10°, the problem arises of concentration of flow on one side and island formation due to heavy silting within the guide bank on the other side. If the river axis is to the right of headwork axis, the concentration of flow is generally generally on the left side with consequent tendency to form an island

Ultimate Bearing Capacity

It is the least pressure which would cause shear failure if the supporting soil immediately below and adjacent to a foundation. The ultimate bearing capacity is defined as the maximum gross pressure intensity at the base of the foundation at which the soil does not fail in shear. When the term bearing capacity is used, it may be understood to be the Universal Building Code

Weathering - Definition and Types of Weathering

It is the process of weakening rock and producing a rock waste or soil cover. Weathering occurs when rocks and minerals comes in contact with the atmosphere, organic life and suicidal water. Essential feature of weathering is that it affects rocks in-situ (in place) and no transportation of material is involved. A part of rainfall always snips into the soil on the covered rocks

Structure Analysis - Introduction and Background

The determination of internal actions and deformations is called Structural Analysis OR The determination of response of the structure to loads. The process of determination can be by: Structural Analysis Softwares Manual manipulations and calculations Structural Analysis consists of: Analysis & Design of a structure

Definition of various Waste Water flow rates

Qavg is the daily average flow based on yearly data.. Normally, the treatment units are designed on the basis of daily average flow while peak and minimum flows are used to check the capacities of basin and conduits in extreme flow condition. Mass Loading Factor takes care for the fluctuation in wastewater flows and the respective characteristics loading parameters.

Traffic Volume Study - Definition, Methods and Importance

The term traffic volume study can be termed as traffic flow survey or simply the traffic survey. It is defined as the procedure to determine mainly volume of traffic moving on the roads at a particular section during a particular time. Toll Plazas are now a day constructed for the collection of revenue from the road users. This process is very efficient for collection of

True Stress & True Strain | Engineering Stress - Strain

The true stress (ø) uses the instantaneous or actual area of the specimen at any given point, as opposed to the original area used in the engineering values. The true strain (e) is defined as the instantaneous elongation per unit length of the specimen. The relationship between true stress and true strain i.e. the flow curve can be expressed using the power law:

Turbine - Definition and Types of Turbines

It is a device which converts mechanical energy into electrical energy or hydraulic energy into electrical energy. Turbines can also be termed as machines extracting energy from fluids. Water driven tubes are used primarily for the development of hydro-electric energy. There can be two basic types of hydraulic turbines. In impulse turbines a free jet of water strikes the

Principles of Zoning in Urban Town Planning

It is the distribution or division of land (in town planning) into particular zones based upon some criteria or principles. The principles of zoning include the following elements which are given importance while zoning an area. Concentric growth: The growth of buildings which spread from a center in all directions is called concentric growth. These types of buildings
