A key design criterion is the requirement that low-pressure blades must be vibrationally tuned in that the lowest several natural modes of vibration must be sufficiently removed from harmonics of running speed during operation. This tuning process is best represented by the Campbell diagram[r]

Results from both techniques fit on the same Arrhenius plot, showing that the slower TGA experiments did not undergo significant sintering over the lower temperature range. Another rapid heating technique is the wire mesh reactor. In this reactor, coal particles are held between two pieces of wi[r]
STEAM AND I NTE RNAL COMBUSTION ENGINES must have a converging-diverging form. The form of this nozzle is contrary to expectation, in that it might be assumed that the continually decreasing cross- section of a purely converging nozzle would be required to accelerate the steam. How[r]
Two classifications of heat exchangers are associated with the steam cycle. These are the condenser located at the exhaust of the steam turbine, and feedwater heaters located in the condensateboiler feedwater cycle that utilize extracted steam from the steam turbine. There are many other heat exchan[r]
Session 5—Understanding the Use Case Model 55 Figure 5-6 Use Case notation for the Use Case diagram By defining Use Cases in this manner, the system is defined as a set of requirements rather than a solution. You do not describe how the system must work. You describe what the sys- tem m[r]
