Must answer all the four questions. Otherwise i will dislike it.


3.15 The inlet and outlet velocity triangles of a particular stage of a turbomachine<br>are given. Answer the following:<br>a. What is the degree of reaction?<br>b. What is the change in stagnation enthalpy across the stage?<br>c. Is this a power-generating or power-absorbing machine?<br>d. What is the energy exchange per unit mass of the machine?<br>Ans: R=0.5; E=60000 ft-lb/slug; power-generating<br>60<br>60<br>W1<br>V2<br>30<br>30<br>150 ft/s<br>W2<br>
