Temperature regions

Due to existence of an isothermal region, temperature of both entrance and outlet was rather lower than that of intermediate section. Where temperature was high, the reaction was sever and fast. So, at site 200-300 mm away from entrance, the temperature was highest, the scale layer was thickest and the whisker column was longest there. The reaction route in this zone could be described as phase reaction homogeneous nucleation — coagulation. When... [Pg.420]

Fig. 2 represents the variation of pH in refrigeration conditions (4°C) and at 20°C (average regional temperature). The samples had initial pH in the range 2.7-3.2. For both situations, the samples reported a decrease in pH. Nevertheless, pH was more stable with refrigeration, except for samples with initial pH between 3.0 and 3.1. In fact these were the more unstable samples in both conditions. [Pg.380]

The regional temperature variations, rainfall, patterns, groundwater flow characteristics, explosive type, explosive concentration, presence of other contaminants, land value, and other regulatory requirements can affect the wetland s cost. Constructed wetlands may not be financially viable at aU sites (D20499J, p. 2 D20503Y, p. 30). [Pg.476]

Local Lapse Rates with regional temperature correction 2450 6.7 14 26 Meyer 1986, 1992 Estimates are corrected for paleolatitude and/or modem sea level. Application uses correction factors for regional affects of continentality and elevated base level (see text)... [Pg.166]

In discussions of atmospheric processes it is useful to divide the atmosphere into different regions. Temperature profiles provide the most convenient basis for this division. Figure 2 shows the altitude profile of atmospheric... [Pg.122]

As shown above, if the initial dissolutional parameters are known (mean annual temperature, type of dissolution system), then the [Ca ] of the cave dripwaters can be estimated Drake and Wigley (1975) demonstrated an empirical correlation between regional temperatures and spring water /7CO2, and thus CO2. The next section summarises the controls on precipitation and translates them into growth rates. [Pg.277]

Additionally a scale of temperature with depth is given using the mean regional temperature gradient of 33°C/1000 m. The temperatures of 115 and 151°C have been marked in Fig. 7. They confine an anomaly of higher rock salt permeabilities. [Pg.182]

An advanced rheometric expansion system (ARES) is used to determine Tg of samples. Strain sweep experiments from 0.01 to 1% strain are conducted to ensure that experiments are carried out in the linear viscoelastic region. All experiments are done at a frequency of IHz and a strain level of 0.05%, which is in the linear region. Temperature sweeps are conducted at a heating rate of 5°C/min over a temperature range which covers the glassy and rubbery regions of the soy flour samples at different water activities. The temperature at which the loss modulus (G") was at a maximum is used to estimate the T . [Pg.597]

Faced with the difficulty of determining plasma composition directly, one is prone to apply equilibrium predictions as a guide to local plasma composition. Referring both to Figures 2 and 3, a highly dissociated composition can be expected in most of the plasma region. Temperatures in excess of 10,000°K., expected over most of the central region of the plasma, would dictate that the atomic species H, C, and N, and their ions would predominate. [Pg.435]

Cylinders With Horizontal Axes. The conduction layer model has been shown to accurately predict the heat transfer for horizontal cylinders [164, 223], but because of the need to iteratively solve for the central region temperature it does not yield an explicit expression for Nu. However, by making additional approximations Raithby and Hollands [223] were able to derive an explicit relation for the heat transfer when the (assumed laminar) conduction layers do not overlap ... [Pg.261]
