The rotor of a gas turbine is turning at a speed of 6,600 rpm when the turbine is turned off. It is observed that it takes 6 min for the rotor to come to rest. Assuming that the motion is uniformly accelerated, determine the number of revolutions the rotor makes before coming to rest.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
