Spotted in Yahoo news, does anyone have a confession to make?!!
Meanwhile, in Australia, a piece of Banksy artwork valued at around \$50,000 (£31,100) has been accidentally destroyed by builders.
The parachuting rat was painted about 15 years ago on a wall in Prahran in Melbourne and has been a proud fixture of the area ever since.
However, it was ruined when builders smashed a hole so that they could put new pipes into the building.
Resident Tina McKenzie told ABC News Australia: “They’ve sawn into the side of the building without actually saying anything.
“But then, that’s builders… they wouldn’t even think”
Ms McKenzie has had dealings with Banksy, and said she was going to send him an email to say a TV crew had been out to film the incident.
When asked what he would do she said: “Well, he would probably laugh that there’s so much attention around something that he’s just done as a part of his lifestyle every day!”j
Assistance Required: Design guidance on Cryogenic system
To Mark/Jim and others who are interested
At the moment I am working on a design check of a liquid nitrogen cryogenic system.
The exact questions / issues that I am looking into are:
1. Standards / Regulations / design guidance as to the materials to be used for the liquid nitrogen line and the cyrovent line.
2. Standards/Regulations for frequency for Cryovent cut ins on Liquid Nitrogen Line
3. Standards / regulations of venting liquid nitrogen boiloff
I have looked at ASHRAE refrigeration guide Chap 47, but this does not seem to have the answers I need. the others around me aren’t sure where else to go.
THe Sub-contractor who is installing the system seems sure of themselves and is stating the original design was inadequate and it should be installed the way they are doing it (which oddly costs more).
(Definition of Cryovent – a port that allows the boiled off nitrogen to escape.)
