Concept explainers

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.

Figure P.16.10 shows a plane truss pinned to a rigid foundation. All members have the same Young's modulus of 70 000 N/mm² and the same cross-sectional area, A, except the member 12 whose cross-sectional area is 1.414A. Under some systems of loading, member 14 carries a tensile stress of 0.7 N/mm². Calculate the change in temperature which, if applied to member 14 only, would reduce the stress in that member to zero. The coefficient of linear expansion a=24x10-/º C. Ans. 5.5°.
5. A Wankel engine (Figure 12-16) uses triangular rotors in a specially shaped combustion chamber to replace the traditional piston and cylinder. As the rotor turns, each of its three sides goes through a four-step cycle. During the intake stroke, fresh air is mixed with fuel as it is drawn into the engine. The rotor then seals off the fuel-air mixture and com- Figure 12-16 Problem 12-5 Intake Compression Power Exhaust mences to com- press it. In the power stroke, the spark plug ignites the mixture. The burning gases expand, adding momentum to the rotor. As the rotor completes its cycle, the burned gases leave the engine through the ex- haust port, and the cycle begins over again. From the above description of a Wankel engine, identify the four thermodynamic processes that drive this device. Can you identify the cycle (Otto, Diesel, Carnot, and so on)?
