Is there a simple way to create a spherical helical path (like a continuous orange peel)? I do not need to start or stop at the poles, near is fine. I basically want to cover a sphere (except near poles) with a continuous tube.
Hi Rosalynn,
I do know that you will want to insulate the slab from the earth as well as reasonably possible. You might start looking at burial grade closed cell glass foam, such as FOAMGLAS from Pittsburgh Corning.
Your glycol source PQ curve and temperature will be needed to finish the...
Hi ParcoEngineer,
I don’t know if your meter has the capacity for multiple calibration points, if so, you may want to calibrate to 0°C (32°F) (melting point of water) and -78.5°C (-109.3°F) (boiling point of carbon dioxide, dry ice). Both these temperatures are easily achieved.
For the 0°C...
Hi Durcan,
I know you had this problem quite some time ago, but hopefully this will help you and others in the future.
We do a lot of vacuum thermal processing for our active heat spreaders. We need to control the surface chemistry of our devices, which is why we use a vacuum.
Sometimes we...
