Don't slove using any ai tools.... QS)89... A steam turbine is governed by throttling. The full load output of the steam turbine, measured at the coupling is 5 MW and losses due to bearing friction, governor and oil pump drive, etc., is 200 kW. The steam is supplied at a pressure of 20 bar and 300°C. The exhaust pressure of steam is 0.07 bar. The internal efficiency ratio of full load is 0.75. Calculate the coupling power of the turbine when the steam flow through the turbine is 20% of that of full load. Assume that external losses are the same as that of full load. Exhaust pressure is the same and internal efficiency ratio is reduced to 70% at this load....A steam turbine is governed by throttling.

The rod is then rotated by a small angle \theta in the counter clockwise direction (positive direction) with respect to the vertical (dashed line), as shown in the following figure. Which one of the following is the net torque (with respect to the hinge) acting on the rod? Use small angle approximation in the final expression, i.e., $\sin \theta \approx \theta$. A A. 0 N\cdot m B. $L(Mg\theta) - L(kL\theta)$ C. $2L(kL\theta) - L(Mg\theta)$ D. $\frac{1}{2}L(Mg\theta) - 2L(kL\theta)$ E. $2L(kL\theta) - \frac{1}{2}L(Mg\theta)$ Once the rod is let go, it starts to do small simple harmonic oscillations around the vertical. The rod's moment of inertia around the hinge is $I = ML^2/3$. What is the angular frequency of the oscillation? [Select] Recall that the torque is given by $\tau = I\alpha = Id^2\theta/dt^2$ where $\alpha$ is the angular acceleration. A. $\sqrt{3g/L - 3k/M}$ B. $\sqrt{6k/M - 3g/L}$ C. $\sqrt{3g/2L - 6k/M}$ D. $\sqrt{6k/M - 3g/2L}$ E. $\sqrt{2k/M}$ In order for the rod to do small simple harmonic oscillations, as discussed in the above, what is the condition that needs to be satisfied? [Select] A. $4kL > Mg$ B. $4kL < Mg$ C. $4kL = Mg$ D. $2kL > Mg$ E. $2kL < Mg$

(d) The system described in part (a) is incorporated into a control loop as shown below, U(s) in + Y(s) out G(s) K where the gain, K, is positive and independent of frequency. Show that the closed-loop transfer function is given by, \frac{1}{1/G + K} Write down the characteristic equation and find its roots (solve) in terms of K, $\tau_1$ and $\tau_2$. What property of the closed-loop transfer function do the roots of the characteristic equation correspond to? Find the value of K = $K_c$ for which both roots are purely real and have the same value.
