Concept explainers

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

A cylindrical machine part moves within a surrounding cylinder. The centrelines of the part and the surrounding cylinder are coincident. The cylinder is full of an oil (viscosity 0.25kg/ms) that is not flowing i.e. no pressure gradient is applied. What is the value of the viscous force exerted on the machine part as it moves along the cylinder at a speed of 9m/s? • The machine part is 0.06m long and has a radius of 0.041m. • The ratio of the machine part radius to the cylinder radius is 0.98. • Assume that the flow is dominated by viscous forces. • Give your answer as an absolute value i.e. no negative sign, in Newtons to one decimal place.

Problem 2 The apparatus sketched in the figure below serves as a viscometer i.e. it can be used to measure the viscosity of a liquid. In the drawing, D is a large reservoir containing a viscous liquid A and E is a cylindrical tube of radius R, open at both ends, surrounding and coaxial with B, which is a cylindrical "bob" of radius êR that is dragged up through the fluid by a frictionless pulley system (C) utilizing a weight W. Determine a design equation that relates the viscosity of the liquid to the geometry of the system and the weight W. Hint: you can assume that the length of the cylindrical tube is sufficiently long for the flow to reach steady state. W E D B
