    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 ?
 
Engineering news on Phys.org
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.
 
Thread 'I need a concave mirror with a focal length length of 150 feet'
I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
