Hi Folks Thanks a lot for those replies, they cleared things up for me here. Philbob

I am examining an application where a pipe running through an underground pit has a puddle flange joining the pipes within the pit wall. My understanding is that the puddle flange will prevent the passage of liquid from one side of the wall to the other (external to the pipe). However a...

Is it possible to determine the heat gain in a liquid due to the action of the pump through which it is being pumped? Is there a rule of thumb to determine this? Any help appreciated.

A colleague of mine has asked if there is a simple rule of thumb to determine the heat gain in a liquid being pumped. i.e. what temperature rise occurs in a liquid due to being pumped at x gal/min through a pump of y hp? Any help appreciated.

A likely way to get a burn is not so much a pipe rupture, but a pressure relief device activating properly and flooding an area with steam. It's tempting to write "Vent to safe location" on a drawing and forget about it. Apologies if this has been raised previously! Philbob

Thats great, thanks for your help folks. PB

I'd appreciate if someone could answer this one. When discussing connection types, e.g. half-inch BSP female etc. what do the letters BSP mean? What does this connection look like? Thanks in advance.

25362 Many thanks for responding to my query, however, I was wondering if there is already published information on the solubility of oxygen in acetone, as we are examining future use of acetone, rather than dealing with an wxisting system Philbob

Can anybody help me on this one? I need to determine the solubility of oxygen (in air) in Acetone. The only information I have on Acetone is its Solubility parameter and Polarity, which may be useful if I compare acetone to a more well known solvent (Water), and scale accordingly, although...
