MetSol

The solution is ammonium chloride/ammonia/water. Because of the NH3Cl I can't use stainless steel. I've tried the newest and best Schott 'Premium' sample bottles and still have the problem of the ammonia escaping when I push it to 110 C. Nothing seems to hold this shit in. Any ideas on what I can buy off the shelf to solve this problem? The samples are only about 100 mL, so we are talking pretty small stuff here.

I'm looking for a system to log data and control motors/heaters/etc on a small pilot plant setup. I plan on using a series of pressure sensors (4-20 mA), thermocouples/RTDs to log the data. I need to find something (like a PLC, maybe), that can both read and log analogue and digital inputs and also control the devices by sending signals back to the motors, etc. I'd like all the comms to be wireless, and in that respect I am way out of my depth. Anybody had experience with this stuff?

The article says litres can be L or l. I disagree. I beleive it is L. All the textbooks I have looked in say that.

They've emptied 4 extinguishers into it and it's still going! I'm in big shit now. I guess I'll have to pay for it and possibly the fire brigade.... This is not a good start to the week.

I'm thinking of purchasing SketchUp, but I' already confused with all the options. Basically all I want to do is 3D model some process engineering plants (pipes, valves, tanks, etc) so I can show the relevant people a simple 3D drawing/rotation. I notice, though, that the free version is limited in the types of files you can save things as and take to other systems. I notice also that it will only print single page drawings. Has anyone else had any experience with this program? Did it meet your needs/expectations? Advice would be much appreciated.

I'm getting around 14 Amps 'per phase'. What does that mean? Surely you don't just add it up? Tell me it's not 3 x 14 = 42 A.... Oh, and it's a pure resistive load (a steam boiler).

Additionally, does anyone know how a solution of ammonia and ammonium chloride in water would behave? I need to calculate heating requirements and eventually try and model behaviour at various temperatures and pressures.

Your help would be much appreciated. I'm running KK on a EeePC. It has internal ethernet. The motel has a high speed ethernet connection but I can't get it to work. Every other time I've been using wireless at home and it seems to just work. Can someone please give me some instruction? I am very limited for time so I apologise for not figuring it out myself. I just don't have the time. Thanks...
