We're trying to get some valves manufactured in Germany, but our drawings have a material spec for SA 53 and SA 105 and that doesn't mean anything to our German machinist. Anyone have the equivalent material numbers for Germany?
As far as I've been able to tell, SA 53-A seamless is Material...
Hi,
I'm trying to find the appropriate standard that specifies requirements for office HVAC capacities. Our contractor tried to tell me that our system is "compliant per ANSI 2000" and that strikes me as suspect, since I don't think I've ever seen an ANSI standard in that format. Plus...

We're using a Platecoil HXer manufactured by Tranter PHE in TX, and I want to know if there are any other companies anywhere that make something similar.
The HXer is basically a single serpentine tube with...
Just wondering if there is a standard rule of thumb for sizing the diameter of an exhaust stack (something along the lines of "for every X cubic feet/hr, increase diameter Y inches"). I'm trying to vent a small enclosure (on the order of 4x4x4) of exhaust gasses and want to make sure there's a...

This is basically part 2 of a previous project: a vapor stream is directed into the mouth of a venturi, which entrains air into the stream, resulting in a mixture. My problem comes from the fact that I don't understand the pressure...
Hi,
I'm trying to calculate the exit conditions of a high-pressure LPG nozzle. I have the dimensions (interior @ state 1 and exit) of the nozzle and the initial conditions of the vapor (P1, T1), as well as the mass flow rate (mdot).
P1 & T1 will give me density (rho)
since mdot=rho*A*V, i can...
