...]. Further, an exterior impervious insulated wall or roof assembly should be provided with some type of natural venting to relieve vapor pressure and allow excess condensate to drain and evaporate. Unfortunately, most condensation problems do not become apparent for 5 to 10 years, long after the one year...

In particular, the development of ASTM Test Method for Determination of Vapor Pressure by Thermal Analysis (E 1782) showed some sporadic exothermic activity near the onset to boiling at test pressures significantly greater than ambient. This exothermic activity is associated with partial...

.... The vapor pressure differential of the inside and outside air determines the driving force of the vapor. The vapor pressure and permeability of the primary and secondary vapor retarders determines how much water vapor may diffuse into the wall cavity. If the temperature gradients at the vapor retarder...

... The effect of flash point reduction and, therefore, the increase of vapor pressure on the design and operation of a supersonic transport (SST) is examined in detail. Considering an SST design, which has been optimized on the basis of a kerosine flash point of 38°C (100°F), the effect on design...

Jet A-2 has a vapor pressure at 38°C (100°F) only slightly greater than Jet A-1 1.0 versus 0.76 kPa (0.145 versus 0.110 psia, respectively). Mixing Jet A-2 with Jet A or Jet A-1...

... Mathematical models have been developed that permit the Reid vapor pressure and the ASTM distillation to be calculated from a low-resolution, gas chromatographic analysis of a gasoline. The accuracy of these calculations is equivalent to that of the standard laboratory test procedures. Results...

... An equation to predict the Reid vapor pressure (RVP) of pure hydrocarbon blends was developed which includes activity coefficients. A comparison of calculated and analytical data shows a standard deviation of 0.15 lb. Applications to predict the RVP of gasoline blends are suggested. vapor...

... Several volatility parameters have been investigated in an experimental study of volatility/emission relationships. These volatility indexes include Reid vapor pressure and several distillation properties. The experimental data show that the fuel tank losses are related characteristically to one...
