Moderate Changes

Creep is rather low or very low, the more so as semi-aromatic polyamides are very often reinforced with high glass fibre contents. It changes moderately when the temperature rises. 

The physicochemical characterization of the acidity of the doped alumina performed by microcalorimetry, has been complementarized with the catalytic test of 2-propanol decomposition [175], It was found that the modification of y-Al203 surface properties with small amounts of Ca ", Li+, Nd ", NF+, SO/, Zf +ions changed moderately its amphoteric properties. The catalytic test of 2-propanol...

The assumption of constant volume is valid for most industrial batch reactors. TTte mass density is approximately constant for a large majority of liquids, even if the temperature changes moderately as the reaction proceeds. Therrfore, the assumption of constant volume is reasonable for batch reactions that take place in the liquid phase. Moreover, if a rigid vessel is filled with gas, the gas volume will be constant because the dimensions of the vessel are fixed and do not vary with time. 

The addition of water depresses zeroth-order rates of nitration, although the effect is very weak compared with that of nitrate ions concentrations of 6x io mol 1 of water, and 4X io mol 1 of potassium nitrate halve the rates of reaction under similar conditions. In moderate concentrations water anticatalyses nitration under zeroth-order conditions without changing the kinetic form. This effect is shown below (table 3.5) for the nitration of toluene in nitromethane. More strikingly, the addition of larger proportions of water modifies the kinetic... 

Dehumidification. Dehumidification may be accompHshed in several ways (see Drying). Moderate changes in humidity can be made by exposing the air stream to a surface whose temperature is below the dew point of the air. The air is cooled and releases a portion of its moisture. Closed cycle air conditioning systems normally effect dehumidification also. The cooled air may require reheating to attain the desired dry-bulb temperature if there is insufficient sensible load in the space. 

Motor nd Drive. The preferred prime mover for a fan is usually an electric motor. Eor fans of low to moderate power, V-belt drives are frequently employed. This permits selection of fans that can be operated over a wide range of speeds rather than being limited to motor synchronous speeds. Furthermore, change of speed is less expensive with V-belt drives. However, fans requiring powerful motors, 37—75 kW (50—100 hp) and higher, are generally directly connected to the motor and driven at synchronous speed. 

Acetate and triacetate exhibit moderate changes in mechanical properties as a function of temperature. As the temperature is raised, the tensile modulus of acetate and triacetate fibers is reduced, and the fibers extend more readily under stress (see Fig. 4). Acetate and triacetate are weakened by prolonged exposure to elevated temperatures in ah (see Fig. 5).
