A small scale power plant that generates electricity using the energy potential of water. Micro-hydro power plants convert the energy of flowing water into electrical energy. The energy produced by them is renewable & the process does not emit polluting gasses.

The pulling out of steel bars from concrete is resisted by the gripping action of concrete known as bond and the resulting stress is called bond stress. The resistance offered to slipping of bars is due to three factors: 1. The chemical adhesion between the two materials. 2. The friction due to natural roughness of bars. 3. The mechanical anchorage of the closely spaced

Civil engineering is field of engineering sciences, related to design, construction and maintenance of buildings, dams, bridges, tunnels, highways and other structures by the use of physical laws, mathematical equations and theories of mechanics. Civil Engineers utilize the available resources (expertise, materials, manpower) to complete the project in the

Solvent is a volatile liquid used to obtain desired viscosity and flow of the paint. It keeps the solid components of paint in suspension and also influences the adhesion properties of the surface.

Rocks normally consist of several minerals, some essential, some accessory. A rock may be thought of as a "mineral environment." Each rock type was formed under certain specific conditions, resulting in the formation of a fairly predictable group of minerals. Rocks fall into three classes according to their origin: Igneous, Sedimentary, Metamorphic. Following are some rocks
