现代填料塔技术例题里面水吸收SO2计算求解决

现代填料塔技术指南 王树楹，主编，例题里面水吸收SO2 计算，P248页，对下图云线部分没看懂，不应该是8.314*T，为啥是0.082*100*T,此处没看懂，请哪位帮忙解释一下，谢谢

Look at the units for the ideal gas constant. R = 0.082 has units of (L atm)/(mol K), whereas R = 8.314 has units of J / (mol K). If the question has pressure and volume expressed in units of atm and liters respectively, you use the R = 0.082 value. If the pressure is expressed in pascals and volume in cubic meters, you use R = 8.314 value (same if pressure is expressed in kilopascals and volume in liters, because 1 kPa = 1000 Pa and 1 L = 1/1000 m^3).

The two R values are the same thing but the reason for the differences is due to having different units. R = 8.314 is actually the more important value because it is expressed in SI units (note that 1 J = 1 Pa * m^3= 1 N/m^2 * m^3 = 1 N * m).

R=PV/T=22.4/273.15=0.082

谢谢，一提醒，就能理解。
