ASPEN 模拟压缩机？ The standard liquid volume flow (Stdvol-Flow) can be very different from the volumetric flow rate of a stream. The standard liquid volume is defined at approximately 60ºF and 1 atm. 标准体积流量是液体在1atm 60F下的体积流量，与体积流量与给定的温度和压力有关，两者是不同的。 你这个选择 体积流量就可以。查看更多
雷德蒸汽压的请教？ reid vapor pressure (rvp) is a common measure of the volatility of gasoline. it is defined as the absolute vapor pressure exerted by a liquid at 100 °f (37.8 °c) as determined by the test method astm-d-323. 也就是说雷德蒸汽压一般只用来描述汽油 冬天汽油的rvp是9~15 psi,夏天值是8~10 psi. 查看更多
