在通风空调、气体净化、化工及冶金等工程计算中,经常要进行不同温度、压力和湿度下气体密度和体积(或体积流量)的计算。在以往的资料中,对于只考虑温度和压力的理想气体的密度和体积的计算方法介绍较多,而对同时考虑气体湿度的实际气体的计算方法则论述较少。因此,下面从这种一般情况出发来讨论湿气体的密度和体积的计算方法。一、湿气体密度的计算任一种气体在标准状态(T_n=273.15°
In the calculation of ventilation, air conditioning, gas purification, chemical engineering, and metallurgy, gas density and volume (or volume flow) calculations are often performed at different temperatures, pressures, and humidity. In previous data, there are many methods for calculating the density and volume of an ideal gas that only considers temperature and pressure, and few methods for calculating the actual gas that considers the humidity of a gas at the same time. Therefore, the calculation of the density and volume of the wet gas is discussed below from this general case. First, the calculation of the wet gas density of any gas in the standard state (T_n = 273.15 °
