The reference temperature that I am using is 180 degrees F. The overall operating temperature range is 70 degrees to 200 degrees.
While some fluid in the system could be at sub-freezing or even sub-zero temperatures at system startup, the lowest operating temperature once the system is...
Thanks to all. The link (Brines.pdf) provided by 25362 was especially helpful. Although, when I approximate the values for Cp from the graphs, it again shows that PG has a higher Cp than EG. I still don't see the evidence to support the statement that EG has better heat transfer capabilities...
In all my reading I have read that Ethylene (EG) has a higher specific heat capacity than Propylene Glycol (PG). Yet when I study the specifications, it seems that the PG actually has a higher specific heat capacity. Which has a higher specific heat capacity?
What is the relationship between...
I am looking for an information source about welding and soldering Type T thermocouple (T/C) extension leads to another extension lead and also to the thermocouple wire.
Specifically information regarding the technique, sources of error, and the pro/cons of welding vs soldering.
Why is there...

What is the proper metod to select diodes to be placed across relay contcts to prevent arcing? What resources are used to identify the diode type? The loads of interest include a 120vac solenoid, a 24vdc door latch and a 12vdc door latch.
