Part 1: Rotating ViscometerOne type of viscometer involves the use of a rotating cylinder inside a fixed cylinder as shown inthe figure below. The gap between the cylinders must be very small to achieve a linear velocitydistribution in the liquid. Design a viscometer that will be used to measure the viscosity of motorSAE 30 oil from 0°C to 100°C.Here you need to determine and report the following parameters:a. The dimensions of the two cylinders, lengths, thicknesses and diameters.b. The gap clearance between the surfaces of the cylinders.c. The rated power of the driving motor.d. The rotational speed of the shaft.e. Assumptions, and operational procedure.Rotating Drum ViscometerDriveMotorRotating CylinderViscos Liquid SampleStationary CylinderFigure 3: Schematic for task 3 part 1.Part 2: Viscosity CorrelationFor the above viscometer:a. Calculate the applied power function of the oil viscosity over the specified range oftemperature. Plot Power function of viscosity.b.

In a rotary viscometer the radii of the cylinders are respectively 50 mm and 50.5 mm, and the outer cylinder is rotated steadily at 30 rad s. For a certain liquid the torque is 0.45 N-m when the depth of the liquid is 50 mm and the torque is 0.81 N-m when the depth is 100 mm. Estimate the dynamic viscosity of the liquid.

Assume the shear area between the fluid layers is 0.5m². To do this you required to explain, with examples, the effects of temperature and shear forces on Newtonian and non-Newtonian fluid. Also, explain the operation and constraints of different viscometers that quantify viscosity in fluids. 2.
