Why pelton turbine is called as impulse turbine?
Water is blasted at the buckets one by one or more jets mounted in the surroundings casing. Momentum is transferred from water to buckets and a torque is created, causing the wheel to rotate. That's why it is an impulse turbine.
Why tripping value of axial shift of steam turbine is more than turbine rotor float?
axial shift depends upon the gap between rotot blade and fixed blade , not on float
How do turbines work?
A simple turbine.Air is drawn into the engine continuously and compressed by a series of rotating blades. Fuel is sprayed into the combustion chamber and burnt increasing the gas temperature to around 1200C.The hot high pressure gas expands through a second set of blades mounted on the same shaft as the compressor blades. The energy of the gas is partially expended powering the compressor, but has a residual energy which is either expended as a hot jet (resulting in thrust) or which drives a further independent set of blades to power a propeller or other device.see http://www.rolls-royce.com/education/schools/how_things_work/journey02/index.html
What are the advantages of free turbine engine over gas turbine engine?
A gas turbine engine will usually yield more power by weight than a piston engine. Main downside is that it can't be throttled very well. Energy efficiency isn't all that good to start with, and will drop right down if it has to be operated outside its optimum range.
What is eddies in volute casing of a centrifugal pump?
In Volute Casing, area of flow increases gradually, Due to this, the amount of movement of water opposite to the general flow of water is more. This movement of water against the actual flow of water is called EDDIES in Volutes casing of Centrifugal pump.Where as in Vortex casing area of flow is uniform and effect of formation of eddies is very less.
What is expansion turbine?
differential expansion is refer to differential distance between rotor blade and fix blade.rotor expand toward generator and casing expand toward control valve.when temperature increase ,expansion in casing and rotor.so rotor mass is less than casing which rotor expand more than casing.
What is positive differential expansion of steam turbine?
Differential expansion means gap between fixed Blade & rotating blase of a turbine.. When steam enters into the turbine, rotor tends to expand towards generator side & casing tends to expand towards control valve side. If differential expansion increase then there is a possibility of reducing axial gap between rotor & fixed blades. When differential expansion is positive its means rotor expand more than the casing expansion. There is a limit upto +ve 5. If increases than +ve 5 it means we have to check front side tie rods status.
Why is it important that the rotor is as high up in the sky as possible on a wind turbine?
Placing the rotor higher up in the sky allows the turbine to access stronger and more consistent wind speeds, increasing energy production. Additionally, higher rotor placement reduces the impact of turbulence and obstacles on the turbine's efficiency.

What factor determines how much electricity a windmill produces?
The main factors that determine how much electricity a windmill produces are the wind speed and the size of the wind turbine's rotor blades. Higher wind speeds and larger rotor blades can generate more electricity. Other factors that can affect electricity production include the efficiency of the wind turbine and the maintenance of the system.
What is helicopter rotor droop?
Helicopters fly by means of an angle of attack increase in the main - rotor disc. However - when this angle of attack increases, the drag experienced on the blades also increases which tends to want to slow the blades down. To avoid that, a gas turbine helicopter engine will have what is called a Power Turbine Governor or PTG. This control unit senses increases in torque values when the pilot pulls up on collective and distributes more fuel into the engine in order to get more output to counter the increase in drag on the rotor blades, thus maintaining a constant rotor RPM in all operating conditions. Rotor 'droop' is when the rotor RPM drops below a minimum given parameter and can be caused by a variety of problems.
How does the area of a wind turbine affect its energy output?
The larger the area of a wind turbine's rotor blades, the more wind it can capture, resulting in greater energy output. This is because larger blades can generate more mechanical energy from the wind, which can then be converted into electrical energy by the turbine's generator.
What is effect if inlet temperature is increased on gas turbine?
Increasing the inlet temperature of a gas turbine can improve its efficiency and power output. This is because higher temperatures lead to better energy conversion and expansion of the gas, resulting in more work output from the turbine. However, there is a limit to how much the temperature can be increased before it affects the materials and components of the turbine, potentially reducing its reliability and lifespan.
How high from the ground is the blades of a 1 MW wind turbine?
The height of a 1 MW wind turbine rotor blade above the ground typically ranges between 150 to 200 feet. This height helps the blades capture more wind energy and generate electricity efficiently.
Can you tell me about the different types of casing used around a door?
There are several types of casing used around a door, including flat casing, colonial casing, and ranch casing. Flat casing is a simple, straight design, while colonial casing has more intricate details. Ranch casing is a wider style that provides a more substantial look. Each type of casing can enhance the appearance of a door and complement the overall design of a room.
Why more energy is produced if the turbine blade of a wind turbine is longer?
no
