Multiple choice

In the velocity diagram shown below, u = blade velocity, C = absolute fluid velocity and w = relative velocity of fluid and the subscripts 1 and 2 refer to inlet and outlet. This diagram is for

  1. an impulse turbine

  2. a reaction turbine

  3. a centrifugal compressor

  4. an axial flow compressor

B Correct answer
Explanation

$\text{Velocity of flow,$\hspace{0.5cm}$}u=u_1=u_2=constant\\ and \hspace{4cm}W_2>>W_1\hspace{8cm}W=\text{Whirl velocity}\\ \text{Hence,it is a diagram of reaction turbine}$
