Composite Material

Composite is consist of two phase, one is Reinforcing phase and other is Matrix. Reinforcing phase is like fibers, particles, flakes. Matrix is a continuous phase. Example of composite: Concrete reinforced with steel, epoxy reinforced with fibers.

Naturally found : Bone-salt plates made of calcium and phosphate ions reinforcement soft collagen.
Some advanced composites are: graphite/epoxy, Kevlar/epoxy, fiber glass etc.

Combined-Cycle Power Plant

Combine Power Plant use both Gas Turbine and Steam Turbine to produce energy. Natural gas use for gas turbine.The exhaust heat of gas turbine use in steam turbine. A schematic diagram are given below: Combined Cycle Generation Process

What is difference between plane angle and solid angle?

A plane angle is one that can be measured completely within a plane. This may be because the angle occurs in a 2-D space, or it is an angle that is contained completely within a plane that is in a 3-D (or higher-D) space. So the angles in a triangle are plane angles, because they are in a plane. Similarly, the angles in a spherical triangle are plane angles, because even though they measure things in a 3-D space, they can always be shown to be wholly within a plane. Another way to consider a plane angle is to think of angles within a circle. You can divide the circle up into 2π radians, for example, or 360°, or 400 gon, or whatever units you choose. However, the radian as a unit is defined by the subtended arc length that is equal to the radius of the circle. A steradian, the basic unit, is solid angle is one that is subtended by a portion of the surface area of a sphere that is equal to r^2, where r is the radius of the sphere. It can be considered to be a cone subtended at...

Francis Turbine Working Principle, Main Parts, Diagram and Application

Turbines using the impulse action of water are the best ones. No it’s not like that reaction turbines are more efficient, when all of this was happening, James B. Francis, an American civil engineer comes up with his turbine called Francis turbine. What’s different he is doing!!! He is just mixing them up. The good’s of both the impulse and reaction turbine, say water enters the turbine radially and exits axially. But that’s not a secret to his turbine efficiency. The magic lies in his amazing design of blades, these blades rotate using both reaction and impulse force of water flowing through them. The ability of francis turbine to use both the kinetic and potential energy to produce power, shorts out a major problem of water head availability as it could be used efficiently for head as low as 50m to as high as 400m and also for a wide range of flow rates which could be as low as 10 meter-cube per second to as high as 700 meter-cube per second. Francis Turbine BA...
