AI Thread Summary
A user is seeking a non-stirred pressure vessel capable of withstanding a minimum pressure of 2,000 psi and a maximum temperature of at least 800°C, with a volume of around 80-100 mL. After a month of searching, they have had little success in finding suitable options. A response suggests that Parr Instruments manufactures the type of reactor needed, providing a link to their products. This indicates that specialized suppliers may be the best source for such equipment. The discussion highlights the challenges in locating high-temperature pressure vessels.

Hi, I was wondering if anyone knew where I could buy a pressure vessel that meets the following specifications:

min. pressure: 2,000 psi
max temp.: at least 800°C
volume: around 80-100 mL

I've been searching for around month now with little success... I could really use some help, thanks!

here is a picture of the type of reactor I need:

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
