Each pump has a specific pumping speed curve, showing the pumping characteristic of the pump as a function of inlet pressure, exhaust pressure, and gas species. Pumping speeds are generally measured and rated either in accordance with the AVS Science and Technology of Materials, Interfaces, and ...
The beginning of the vacuum cooling stage was marked by the closure of the vessel and the activation of the vacuum pump. 2.4. Process parameters and analytical determinations The parameters determined for each process were global weight loss, cooking weight loss, cooling weight loss and the mean ...
Intensity noise-induced acceleration Successful cavity cooling requires that the local intensity maximum follows the maximum of the coupling curve in time, ideally with a phase lag of 90°. Only then the particle will climb higher than it falls in the potential well, which is modulated by the p...
Note that the dielectric function of intrinsic Si was assumed to be independent of temperature in the range of operation and was obtained by curve-fitting the experimental data from ref. 50. Theoretical curves of heat rate Q as a function of the temperature difference DT between the emitter ...
Test the range of boiling points for petroleum and biofuel products with this vacuum distillation system. The sample is distilled at a reduced pressure and the initial and final boiling points are measured. A distillation curve can be generated relating volume percent distilled and the atmospheric eq...
Figure 2. Cooling curve of fresh-cut frillice iceberg (a), romaine (b), and red oak leaf (c) lettuce, and chamber pressure and temperature changes during the vacuum precooling process. 3.2. Shelf life Evaluation The shelf life of fresh-cut vegetables was determined by two criteria, visual...
The mass curve indicates that condensation occurs at a constant rate, however the evaporation rate increases in time due to the increasing temperature of the water in vessel 2. During condensation in vessel 2, the pressure is slowly reaching a pressure close to the water equilibrium pressure 62.6...
A semi-retired electronics designengineer by trade, he has previously covered the development of the curve tracer on Instructables for theversion 1andversion 1.1. What this device essentially allows you to do is sweep the connected tube through its input parameter ranges, while observing the resulti...
A screw vacuum pump includes a gas working chamber formed by a male screw rotor and a female screw rotor respectively including unequal lead screws engaging each other and having a
