Am currently designing a dilute phase pneumatic transfer system to convey a dense powder. Have a 6 foot lift and a 2 foot lift with about 30 feet horizontal between 2 lifts. Question - should "horizontal" pipe (between 2 lifts) be horizontal, sloped up or down from 1st to 2nd lift. Can find...
Our plant has had several problems recently related to accurately measuring high temperature (~500C) surfaces using spring loaded flat tip stainless sheathed thermocouples. In several cases the reported surface temperature is up to 100C below what we think the actual temperature is. How? When...
Our plant has several places where plastic tubing (typically Tygon) has been used to temporarily connect 2 lenghts of pipe. This has been done when piping mods were required and the pipe fitters couldn't weld or thread the pipe (due to many reasons). These are low pressure situations (<15...
I recently posted a question in the Heat Transfer & thermo forum which might better be suited here. The question was related to which was better for a building HVAC system Chilled Water or DX. I would appreciate any response to the other forum.
Over a 10 year period which is better CW-HVAC or DX-HVAC?
For our application is "cold recovery" economically viable?
We have a large plant in the Southeast with several Chilled Water systems that supply CW to our buildings for HVAC. We are planning to build a new metal building...
