A ball park figure for the weight of a double decker bus might be about 15,000 kilograms. But to calculate the centrifugal force on a turbine blade with this hanging from it would require the blade length and the rotational speed of the turbine.
What are the main reason of turbine blade failure?
In order to enhance creep life of gas turbine blade, it is required to keep blade at lower temperature, hence internal cooling of blade is done.
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.
Resistance offered by turbine to the steam
one rotor blade and one stator blade make up a stage of the turbine. after crossing every stage the pressure of the steam reduces.
Another name for a turbine blade is a vane.
What are the main reason of turbine blade failure?
The Second Stage Turbine Blade was created on 2002-02-05.
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
turbine blade angle is that angle with which,a high presseure & high temprature steam is made to empenge on it.

wind pushes on the blades of the wind turbine which pass on this motion to the generator to produce electricity. The energy and the speed of a wind turbine depend on the blade pitch control which depends on the angel of the blade chord to the plane of rotation. The blade pitch determines the speed of the turbine which also depends on the wind speed. Energy is directly proportional to the speed of the turbine. Therefore, the energy produced by a turbine depends on both the wind speed and the blade pitch angle. By: Amin Elsersawi
one stage is the combination of one moving blade and fixed blade.
