  • Chapter 7.2 - Entropy: A measure of disorder. The objectives of this chapter are to: Derive the reversible steady-flow work relations; develop the isentropic, or adiabatic, efficiencies of various steady-flow engineering devices and apply the definitions to turbines, compressors, and nozzles; introduce and apply the entropy balance to various systems.

  • Pipe stress analysis calculates the stress in a piping system subject to normal operating loads such as pressure, weight, and thermal expansion, and occasional loads such as wind, earthquake, and water hammer. Because all piping systems are connected to equipment such as vessels, tanks, pumps, turbines, and compressors, the piping stress analysis also involves evaluation of the effect of the piping forces and moments to the connecting equipment. As the piping stress is controlled by the arrangement of the supports and restraints, the scope of piping stress includes also pipe supports.

  • The late 1940s through the 1950s saw rapid technological advancement and the introduction of rotating equipment. Larger and higher horsepower equipment came into use. This brought about the need for more “power-dense” flexible couplings with greater misalignment, which had to be accommodated. Around this time the fully crowned gear spindle (Figure 1 S A ) was developed and introduced into the steel industry. Also during this period, the use of the gas turbine in industrial applications (generators, compressors) was becoming popular.

  • The term magnetic bearing refers to devices that provide stable suspension of a rotor. Because of the contact-less motion of the rotor, magnetic bearings offer many advantages for various applications. Commercial applications include compressors, centrifuges, high-speed turbines, energy-storage flywheels, high-precision machine tools, etc. Magnetic bearings are a typical mechatronic product. Thus, a great deal of knowledge is necessary for its design, construction and operation.

  • Another significant driver—in a world now more environmentall conscious than ever—is a global thrust to develop projects whic not only minimize GHG emissions but also help to displace GHG emissions from other industrial sources. Thus, one of the more significant advantages of gas-turbine and engine-based cogeneration is the potential for significant GHG reductions. Further, it is the monetization of GHG reductions and other poss financial incentives that are helping to encourage and facilitate development of cogeneration applications.

  • Chapter 5 (Part 2) - Mass and energy analysis of control volumes. The objectives of this chapter are to: Solve energy balance problems for common steady-flow devices such as nozzles, compressors, turbines, throttling valves, mixers, heaters, and heat exchangers; apply the energy balance to general unsteady-flow processes with particular emphasis on the uniform-flow process as the model for commonly encountered charging and discharging processes.
