Air - Density and Specific Volume vs. Altitude Density and specific volume of air varies with elevation above sea level. The density of air varies with pressure (the Ideal Gas Law) and the altitude above sea level. Mean absolute pressure at sea level is approximately 760 mmHg (101.325 kPa...
An apparatus for adjusting the specific volume of intake air for an engine has an orifice (5) for controlling the amount of air to by-pass a throttle valve. The apparatus is provided with a lattice-shaped heating element (8) which is disposed on the downstream side of the orifice. Thus,...
accelerator operation rate, an engine speed and an air-fuel ratio, and correcting a control valve operation rate according to an actual value of the specific volume of intake air and its target value at a normal running in operation of a control valve of the specific volume of intake air.收...
Specific volume of moist air is defined as the total volume of humid air per mass unit of dry air
1) air specific volume 空气比容 2) humid volume 湿空气比容 3) air specific heat ratio 空气比热容比 1. When using connetcion number,we can know the uncertainty in calculatingair specific heat ratioexperiment objectively. 利用联系数客观地刻划出空气比热容比实验不确定度计算中存在的不确定性,据此改进...

air specific humidity; latent-heat flux; sea surface temperature; FY-3C Graphical Abstract1. Introduction Air–sea latent heat flux (LHF), combined with momentum flux and sensible heat flux, represents an important aspect of the atmosphere–ocean interaction, energy budget, water cycle variability,...
In the study, the relative specific heat of mono and hybrid nanofluids is compared for different volume concentrations, between 0.01% and 0.03%, under room temperature conditions. The experiments revealed that the relative specific heat of Al2O3–SiO2/H2O hybrid nanofluid is higher than Al2O3/...
The wavelength shift with pressure of the ruby R//1 fluorescence line ( DELTA lambda ) has been calibrated in the diamond-window pressure cell from 0. 06 to 1 Mbar. This was done by simultaneously making specific volume measurements of four metals (Cu, Mo, Ag, and Pd) and referring thes...
