1. A rotating cylinder viscometer was used to find the dynamic viscosity of SAE 10W-30 oil at 130°F. The value found was close to the one you would obtain from the chart in English units. The cylinder is 2.5" in diameter and 2.5" high. The height of the rotating cylinder in contact with oil is 2," and its diameter is 2'". The rotating cylinder is moving about the central axis. Find the power required to rotate the cylinder at 50 rpm. (Hint: First, find torque. Find angular velocity, which is 2II0/60 and Power = Torque X angular velocity).
