The discussion revolves around converting the ideal gas law equation PV=nRT to the form PQ=ṁRT, where Q represents volumetric flow rate and ṁ denotes mass flow rate. Participants are seeking clarification on how to express Q and ṁ in this context. The conversation also touches on the geometry of gas flow, questioning whether it pertains to flow in a pipe or another configuration. The teacher has indicated that this transformation is indeed possible. Understanding the relationship between volumetric flow rate and mass flow rate is crucial for this conversion.
