In order to better interpret the fire-induced pressure variation in air-tight compartment fires, the present paper discusses the energy balance equation starting from a commonly used form, taking into account the mutual influence between compartment pressure and ventilation behavior. The obtained ...
Based on the changes in the PL intensity with the oxygen pressures, a possible mechanism for the observed photoluminescence is suggested. The present results provide a route for room-temperature response of oxygen in the gallium oxide nanostructures. 展开 ...
Pressure values corrected for humidity at varying temperatures were employed to determine the density of moist air. Using the corrected moist air densities, ... M Assiamah,D Mavunda,TL Nam,... - 《Radiation Physics & Chemistry》 被引量: 4发表: 2003年 Transonic flow of moist air around the...
The wind load sections of most building codes [1], [2] suggest approximate mean pressure coefficients for common building shapes. In addition to wind load calculations, wind pressure coefficients are also required in the estimation of air infiltration into buildings [3]. Air infiltration is highly...
Segmental perfusion pressure (SPP) equation for the intracranial compartment Applying the Thevenin equivalent model to describe the distribution of the blood flow between intracranial and extracranial compartments of the head, we derived the segmental cerebral perfusion pressure equation for the intracranial ...
In this formula, the variable PG stands for pressure gradient, PD stands for pressure difference, and D stands for distance. What is an example of a pressure gradient? The most consistent pressure gradient in Earth's atmosphere is the decrease in air pressure that occurs as altitude increases....
Surface pressure reduction in hurricanes is calculated by applying the total energy equation (TEE) to ideal isentropic upflow in a vertical tube. The pressure reduction at the base of the tube, called the intensity , is calculated for three upflow processes: reversible upflow of air approaching eq...
For evaporation and sublimation processes,dp/dTexpresses the change in the saturation vapor pressurepwith the temperatureT,whereas for the processes of fusion and polymorphic transformation,dT/dpdetermines the change in the transition temperature with the pressure. In other words, the Clausius-Clapeyron...

Designing Combustion Engines: To optimize fuel use and minimize emissions. Food Packaging: To calculate the ...
The evolution equations for nonlinear Scholte waves (finite amplitude elastic waves propagating along liquid/solid interface), which account for the second order nonlinearity of a liquid, are derived for the first time. For mathematical simplicity the nonlinearity of the solid, which influence is expec...
