I am Les mt Amst Grinen, 1. Inside Diameter of cylindu, D = 15em D = 0.15m Outsida diameter of cylinder , Do = 15.8cm Do=0:15O. 158 -0.15 Since, dy = 0.158-0.15 dy = 0.004 m çdy do odel 2 0.004 m Now, du = U-0 = 7.065 m/s Hence, Shem sabe a delay = 0

Thanx, please upvote.

    A viscometer is an instrument for measuring the viscosity of a fluid. In a simple form, it consists of two concentric cylinders, with the outer cylinder fixed and the inner cylinder free to rotate. The space between the two cylinders is filled with the fluid in question, and the torque required to rotate the inner cylinder at a constant speed is measured. One such device consists of two 21.0-cm long cylinders, one 15 cm in diameter and the other 15.4...
