    Process Stream
AI Thread Summary
In a process stream, key properties typically measured include mass flow, pressure, temperature, and composition. Steam quality, or dryness fraction, is crucial but often cannot be measured directly. Most thermodynamic properties, like enthalpy and entropy, depend on steam temperature. Additionally, moisture content can be effectively measured using microwave technology. Understanding these parameters is essential for optimizing process efficiency.

what are some chemical or physical properties that are typically measured in a process stream ?

Typically mass flow, pressure and temperature. You might also measure composition of the process stream itself depending on the exact process.
 
Similar to the answer given by rock.freak667, the parameters usually measured are temperature, pressure and flow rate. Most properties (such as enthalpy, entropy, etc.) are simply functions of the steam temperature.
One important point to add is that the steam quality (dryness fraction) is an important parameter which should be known but cannot, under most circumstances, be measured directly.

I'm not sure what "dryness fraction" means when characterizing steam quality. I can say, however, that the moisture content in a flowing process is simple to measure using microwaves.
 
I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...
