What are the stages in steam turbine?
Classifications of steam turbines: According to Principle: 1. Impulse Type 2. Reaction Type. According to Application: 1. Condensing 2. Non-condensing
What is the length of an blade for a gas turbine?
The length of a blade depends on the style (impulse or reaction), the overall size of the turbine, whether it is an axial flow or radial flow turbine, and where the blade is located within turbine of an axial flow turbine. One thing that is constant: the length of the blade increases from the steam or gas inlet to the discharge of the unit. The profile will gradually increase in diameter from inlet to discharge.
What is the impulse turbine mechanism?
Impulse turbine Mechanism deals with the Impluse force action-reaction . As we all know the Netwon 3rd law of motion," Every action has equal and opposite reaction", the same is work on this. As the water fall on the blade of the rotor it generate the impact force on the blade surface, The blade tends to give the same reaction to the fluid, but the rotor is attached to the rotating assembly, it absorb the force impact and give the reaction in the direction of the fluid flow.Thus the whole turbine rotates. The rotation speed of the turbine depends on the fluid velocity, more the fluid velocity, greater the rotation speed, ans greater the speed means more power generation. regards, Alpesh Prajapati india.

What does the turbine do in a generator?
A turbine is a rotary engine that extracts energy from a fluid flow and converts it into useful work.The simplest turbines have one moving part, a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades, or the blades react to the flow, so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and water wheelsGas, steam, and water turbines usually have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to the British Engineer Sir Charles Parsons (1854-1931), for invention of the reaction turbine and to Swedish Engineer Gustaf de Laval (1845-1913), for invention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.A device similar to a turbine but operating in reverse, i.e., driven, is a compressor or pump. The axial compressor in many gas turbine engines is a common example. Here again, both reaction and impulse are employed and again, in modern axial compressors, the degree of reaction and impulse will typically vary from the blade root to its periphery.
Should a katana ordered online have oil on the blade when it arrives?
Blades have oil on them to protect from rusting. Rust is a reaction between the metal an oxygen in the air. I would fully expect the blade to have some amount of oil on it to protect it.

What pushes an aircraft?
The type of "push" most commonly of interest in aircraft are from reaction-based engines which create needed forward thrust to produce lift. The reaction that creates the thrust is implicit in the name "aircraft"; a common illustration would be the blade of a propeller pushing against air; the force of the reaction against the blade pulls on the aircraft by virtue of the fixed connection to the engine; the consequent motion of air across the lift surfaces (typically, wings) generate the lift. Other devices which create this reaction include jet engines, turboprops, rocket engines (rarely), and the like.
What noun is used with a blade of?
The most common nouns that may be used with 'a blade of' may be a 'blade of grass' or a 'blade of steel'. There are other terms for a blade, for example the blade of a knife, the blade of a razor, or the blade of a lawnmower, etc.However, the noun 'blade' can also be used in an abstract context, for example:He wields the blade of power while I wield the blade of labor.
Who played blade in blade trinity?
Wesley Snipes, he played blade in all of the Blade movies.
What nicknames does Robert Blade go by?
Robert Blade goes by Blade.
Why is it necessary to have the tail rotor on the helicopter that spins perpendicular to the spin of the main rotor?
"For every action there is an opposite and equal reaction." For the helicopter to make the blade move in one direction, the blade will try to make the helicopter move in the opposite direction. Since the blade tries to make the helicopter spin, something is needed to keep the helicopter from spinning. So the manufacturer puts a tail rotor on the helicopter.
What are the designations of a three-prong plug?
On a three prong plug there will be a neutral blade, a "hot" blade and a ground blade. The neutral blade is wider that the "hot" blade. In North America the ground blade is "U" shaped.
