What is the frequency of fundamental note of 0.2 metre long open pipe.Velocity of sound in air is 322 m/s

To maintain a rotor at a uniform angular speed of 200 rad s~ 1, an engine needs to transmit a torque of 180 Nm. What is the power required by the engine? (Note: uniform angular velocity in the absence of friction implies zero torque. in practice, applied torque is needed to counter frictional torque). Assume that the engine is 100 % efficient.

What type of inertia are there? What are they?

What is conductance? What is its unit?

What is momentum ? What is its unit ?
