Mechanical Engineering A turbine is running at rated power of 5 MW with the low speed shaft spinning at 12 RPM, with a wind speed of 10 m/s. The drive train has a polar moment of intertia of 50 million kg-m2. The wind suddenly increases in speed to 12 m/s for a 10 second period. What will be the speed of the rotor after that 10 second period, if no control changes are made to the turbine (i.e power delivered to the grid continues at 5MW, and no change in blade pitch angle, no change in Cp, etc.).

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
