2C.4 Falling-cylinder viscometer (see Fig. 2C.4). A falling-cylinder viscometer consists of a long vertical cylindrical container (radius R), capped at both ends, with a solid cylindrical slug (ra- dius KR). The slug is equipped with fins so that its axis is coincident with that of the tube. One can observe the rate of descent of the slug in the cylindrical container when the lat- ter is filled with fluid. Find an equation that gives the viscosity of the fluid in terms of the ter- minal velocity of the slug and the various geometric quantities shown in the figure. Cylindrical slug descends- with speed t -XR- Cylindrical container filled with fluid Fig. 2C.4 A falling-cylinder viscom- eter with a tightly fitting solid cylin- der moving vertically. The cylinder is usually equipped with fins to maintain centering within the tube. The fluid completely fills the tube, and the top and bottom are closed.

Which of the following statements about an oil’s viscosity is not true? a. The ability of oil to resist flow is its viscosity. b. Viscosity is affected by temperature; hot oil flows faster than cold oil. Oil flow is important to the life of an engine. c. In the API system of oil viscosity classification, the lighter oils receive a higher number. d. Heavyweight oils are best suited for use in high-temperature regions. Low-weight oils work best in low temperature operations.
