An impulse turbine has a mean blade speed of 300 m/s. The speed of the turbine wheel is 230rpm. The nozzle angle is 20∘, and the gas leaves the nozzles at a velocity of 800 m/s with a mass of 2 kg. The blade outlet angle is 20∘, and the coefficient of friction is 0,75 6.1 Construct a velocity diagram in LANDSCAPE orientation. Label all angles and velocity values in m/s. Use a scale 1 cm=50 m/s. 6.2 From the diagram, determine: 6.2.1 The blade inlet angle 6.2.2 The angle leaving the turbine 6.2.3 The power in kW
