Part 1: Rotating Viscometer One type of viscometer involves the use of a rotating cylinder inside a fixed cylinder as shown in the figure below. The gap between the cylinders must be very small to achieve a linear velocity distribution in the liquid. Design a viscometer that will be used to measure the viscosity of motor SAE 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 Viscometer Drive Motor Rotating Cylinder Viscos Liquid Sample Stationary Cylinder Figure 3: Schematic for task 3 part 1. Part 2: Viscosity Correlation For the above viscometer: a. Calculate the applied power function of the oil viscosity over the specified range of temperature. Plot Power function of viscosity. b. Fit the viscosity function of temperature of the above motor oil to the following logarithmic quadratic correlation as described below. Find the values for the constants a, b, and c. Take Ho at To =0 °C. In - a + b In4.
