The answer of this question is B. 22x + 20
The periodic table is in increasing atomic mass. Hope this helped.
The velocity at the end of vaneless space(state 3) is 965.92 m/s
<h3>What is centrifugal compressor?</h3>
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.
