Which of the following represent(s) Euler turbo-machine equation?
I) \(P_w = \omega T = \rho Q (u_2 V_{t2}-u_1 V_{t1})\)
II) \(H = \frac{p_w}{\rho gQ} = \frac{1}{g} (u_2 V_{t2}-u_1 V_{t1})\)
III) \(Q_{weir}=C_d b\sqrt{g} \left(H + \frac{v_1^2}{2_g}\right)^{\frac{3}{2}} \approx C_d b\sqrt{g} H^{\frac{3}{2}}\)
