Question
![8.4 The later stages in an axial flow turbine are reaction-type stages. In one such stage,
the degree of reaction is 50%. The mean radius and height of the rotor blades are 3
in. and 1 in., respectively. The speed is 40,000 rpm and the flow coefficient þ=0.24.
The rotor exhaust temperature and pressure are 60°F and 14.7 psia, respectively.
If V12 = 1100 ft./s, calculate the following: (a) nozzle angle, (b) blade loading coef-
ficient, (c) total temperature at the stage inlet and exit, and (d) power. Also, show
the process on a T-s diagram.
Ans: az=78.13°; ự =1.1; To2=727°R; To3=525.5°R; power=171 hp
