Question:
If there are no guide vanes, \( C_1 \) will be radial (\( \alpha_1 = 90^\circ \)), then this particular condition is expressed as
If there are no guide vanes, \( C_1 \) will be radial (\( \alpha_1 = 90^\circ \)), then this particular condition is expressed as
Show Hint
Zero whirl occurs when the absolute velocity enters radially.
