The blades of an axial flow turbine have the aerofoil shape... Also,for the axial flow turbines... Vf1=Vf2 The water strikes the blade surface at the same time from the root to its tip and a stream of water will leave the water at the correspondin trailing edge. Therefore,for inlet to outlet,the radius and blade velocity will be the same,BUT the blade velocity will be different at different sections of the blade due to variation in the radial distance,which implies that the velocity triangles for each section of the blade will be different.In order to achieve shockless flow,the inlet and outlet triangles of a blade must vary from root to its tip,and therefore,axial flow turbine blades are twisted...

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.

Another name for a turbine blade is a vane.
the peripheral velocity of the turbine is the around velocity. the increase in the velocity of the peripheral will decrease the velocity of the flow towards the turbine
What are the main reason of turbine blade failure?

Whirl velocity of a turbine is determined by how fast the turbine can turn when it is moving. This is a factor considered with airplane manufacturing. Whirl velocity is the number of times in a second that a turbine can rotate, moving at a given speed.
The main function of a wind turbine blade is to capture the energy from the wind and convert it into rotational energy to spin the turbine and generate electricity. The design of the blade is crucial in maximizing energy capture efficiency and overall turbine performance.
turbine blade angle is that angle with which,a high presseure & high temprature steam is made to empenge on it.

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.
