Given a radial hydraulic turbine in which the water enters theperimeter and exits in the center in the direction of the axis.
The outer diameter of the blades cm120, and their inner diametercm80. Blade thickness (parallel to the axis) cm20.
The water enters at an angle of 20 ° from the tangent to therotor, and 30 from the blade.
The exit angle of the blade is 30 ° from the radialdirection.The rotational speed is 80rpm, and the power is 9m 3 /s
1.What are the magnitudes of all the velocities (of the flow andof the blades, absolute and relative), at the entranceAnd at the exit? The speed triangles at the entrance and exit mustbe drawn.
2.What is the power transmitted by the fluid to theturbine(assuming there is no friction or other lossesIn the blades)?
3.Is the power calculated in section B the maximum possible? Ifso - must be explained in detail;If not, what needs to be changed in the blade to get maximum power,and what is the maximum power?
