3. The viscosity of liquids can be measured through the use of a rotating cylinder viscometer of the type illustrated in Fig. P1.3. In this device the outer cylinder is fixed and the inner cylinder is rotated with an angular velocity w. The torque T, required to develop w is measured and the viscosity is calculated from these two measurements. Develop an equation relating μ, w, T, e, Ro and Ri. Neglect end effects and assume the velocity distribution in the gap is linear.

If 10 m^3 of atmospheric air at 1 degree centigrade temperature are compressed to a volume of 1m^3 at 100°C, what will be the pressure of air?

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

Example 3.8.In Example 3.7 we considered a vacuum system with zero leaks. No real vacuum systems aretotally leak-free; engineers work very hard to keep the leakage rate as low as possible. If thetank in Example 3.7 has a leak of 0.0001 lbm/min of air, what will the pressure-time plot looklike, and what will be the final pressure?      ex: 3.7 is posted

The flow velocity is not changing with time but changing with spaceb. The flow velocity is changing with both time and spacec. The flow velocity is changing with time but not changing with spaced. The flow velocity is not changing with both time and space   3. The below figure shows a pipe with a circular cross section of diameter D mm on the left end and a square cross section with side D mm on the right end. Mercury enters the left end with a velocity 1 cm/s and leaves the right end with a velocity V2. Find V2 (neglect losses in the pipe).a. Cannot be find since length is not givenb.

Suppose your bicycle tire is fully inflated, with an absolute pressure of 7.00 X 105 Pa (a gauge pressure of just under 90.0 lb/in2) at a temperature of 18.0oC. What is the pressure after its temperature has risen to 35.0oC? Assume that there are no appreciable leaks or changes in volume.
