Given the torque necessary to maintain the indicated angular velocity, obtain the dynamic viscosity of the fluid which occupies the space that separates the two concentric cylinders. The velocity gradient is assumed to be a straight line. Use 2 decimal places. Remember from prior subjects: T, Torque = Force x moment arm, which is the radius of the movable part = F(r) U, Velocity = Radius of the movable part x Angular velocity = (r)(ω)

Question

Given the torque necessary to maintain the indicated angular velocity, obtain the dynamic viscosity of the fluid which occupies the space that separates the two concentric cylinders. The velocity gradient is assumed to be a straight line. Use 2 decimal places.

Remember from prior subjects:

T, Torque = Force x moment arm, which is the radius of the movable part = F(r)

U, Velocity = Radius of the movable part x Angular velocity = (r)(ω)
