Power Plant Layouts

Geothermal power plants:-

Geothermal power plants use hydrothermal resources which have two common ingredients: water (hydro) and heat (thermal).
Geothermal plants require high temperature (300 to 700 degrees Fahrenheit) hydrothermal resources that may come from either dry steam wells or hot water wells.
We can use these resources by drilling wells into the earth and piping the steam or hot water to the surface. Geothermal wells are one to two miles deep.

Flash/Binary Combined Cycle:-

This type of plant, which uses a combination of flash and binary technology, has been used effectively to take advantage of the benefits of both technologies.
In this type of plant, the portion of the geothermal water which “flashes” to steam under reduced pressure is first converted to electricity with a backpressure steam turbine and the low-pressure steam exiting the backpressure turbine is condensed in a binary system.

MECHANICAL PROPERTIES OF A METAL



mechanical properties of a metals are Brittleness, Creep, Ductility, Elasticity, Fatigue, Hardness, Malleability, Plasticity, Resilience, Stiffness, Toughness, Yield strength.

Often materials are subject to external force when they are used. Mechanical Engineers calculate those forces and material scientists how materials deform or break as a function of force, time, temperature, and other conditions. Materials scientists learn about these mechanical properties by testing materials.
Some of the important mechanical properties of a metals are Brittleness, Creep, Ductility, Elasticity, Fatigue, Hardness, Malleability, Plasticity, Resilience, Stiffness, Toughness, Yield strength.

Above mechanical properties of metals are explained below in brief.

Brittleness : Tendency of a material to fracture or fail upon the application of a relatively small amount of force, impact or shock.

Creep : When a metal is subjected to a constant force at high temperature below its yield point, for a prolonged period of time, it undergoes a permanent deformation.

Ductility : Ductility is the property by which a metal can be drawn into thin wires. It is determined by percentage elongation and percentage reduction in area of a metal.

Elasticity : Elasticity is the tendency of solid materials to return to their original shape after being deformed.

Fatigue : Fatigue is the of material weakening or breakdown of material subjected to stress, especially a repeated series of stresses.

Hardness : Hardness is the ability of a material to resist permanent change of shape caused by an external force.

Malleability : Malleability is the property by which a metal can be rolled into thin sheets.

Plasticity : Plasticity is the property by which a metal retains its deformation permanently, when the external force applied on it is released.

Resilience : Resilience is the ability of a metal to absorb energy and resist soft and impact load.

Stiffness : When an external force is applied on a metal, it develops an internal resistance. The internal resistance developed per unit area is called stress. Stiffness is the ability of a metal to resist deformation under stress.

Toughness : When a huge external force is applied on a metal, the metal will experience fracture. Toughness is the ability of a metal to resist fracture.

Yield strength : The ability of a metal to bear gradual progressive force without permanent deformation.

Welcome to India 2012 Documentary

Learning how to survive on an increasingly crowded planet is probably our ultimate challenge. But there is one place, home to over a sixth of the worlds population, which is already making a good shot at adapting: welcome to India. This extraordinary observational series casts aside the usual preconceptions about the sub-continent, and lets a few of Indians 1.2 billion show how their world really works.
