Impact of compression pressure on tablet appearance.
The color of model tablets deepened and tablet gloss increased with increase in compression pressure regardless of colorant type. The possible reasons for these phenomena were examined. These observations could not be explained either by polymorphic transition of the colorant or by condensation of the colorant during compression. Instead, a change in surface roughness was assumed to be the most...
متن کاملLow pressure adsorption of CO2 on multi-wall carbon nanotubes
Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...
متن کاملInfluence of Altitude Atmospheric Pressure on Octane Requirement (RESEARCH NOTE).
The normal specifications of motor gasolines as well as their combustion characteristics in internal combustion engines are reviewed in this paper. The effective factors influencing the fuel performance, such as the molecular structure of the fuel constituents, the operating conditions and the atmospheric pressure and temperature are also discussed. A relationship between the optimum octane num...
متن کاملMaterials on Dies for Pressure Die Casting
In the contribution the stress of die materials of thermal fatigue is defi ned and material life is derived theoretically and compared with the measured values. The important properties of the die materials as thermal conductivity, coeffi cient of thermal expansivity, modulus of elasticity and mechanical properties are described. Binding to it single die materials as carbon steels and chrome-tu...
متن کاملInfluence of Pipeline Operating Pressure on Value Setting of Automatic Control Valves at Different Pressure Drop Rates
When a natural gas pipeline ruptures, the adjacent upstream and downstream automatic control valves (ACV) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ACV actions. If the DPS is not properly adjusted, the ACV may mistakenly close or it may not take any actions at a proper ti...
