This paper presents a simple setup to investigate the continuous gas dilution process. The setup consists of vessels and an oxygen sensor. Two experiments have been conducted. First, by flowing nitrogen (N2) into a vessel containing ambient air, the oxygen (O2) concentration depletes following an exponential decay. The decay constant depends on the vessel's volume and the flow rate. Second, in a series of dilution, two vessels are connected. The first vessel (#1) contains ambient air, and the second (#2) contains N2. The flow of N2 through this setup will dilute the O2 that can be monitored in vessel #2. The pattern of this dilution is characterized by the volumes of both vessels and the flowrate. Finally, these simple experiments show a strong agreement between the calculated and measured quantity related to the dilution.

本科生气体稀释实验

本文介绍了一个简单的设置来研究连续气体稀释过程。该装置由容器和氧传感器组成。进行了两次实验。首先，通过将氮气 (N2) 流入装有环境空气的容器中，氧气 (O2) 浓度会随着指数衰减而耗尽。衰减常数取决于容器的体积和流速。其次，在一系列稀释中，连接两个容器。第一个容器 (#1) 包含环境空气，第二个容器 (#2) 包含 N2。通过此设置的 N2 流量将稀释可以在容器 #2 中监测的 O2。这种稀释的模式以两个容器的体积和流速为特征。最后，这些简单的实验表明，与稀释相关的计算量和测量量之间存在很强的一致性。
