For a centrifugal compressor, the flow at the exit of the blade (state 2) has a velocity of 250 m/s with an angle of 15 degrees to the wheel tangent (75 degrees to the normal)

Respuesta :

The velocity at the end of vaneless space(state 3) is  965.92 m/s

What is centrifugal compressor?

It increases kinetic energy to the airstream using a rotating element and then converts it into potential energy in the form of pressure.

Temperature at state 2, T₂ =T₀ + c/2Cp

Substitute T₀ =450K, c=250m/s, Cp =1005, we get

T₂ =418.90K

From the velocity triangle, sinβ₂ =c₂/v₂

v₂ = 250/sin (90°-75°) = 965.92 m/s

Thus, the velocity at the end of vaneless space is 965.92 m/s.
