Can anyone advice me what are the steps requires for Line Sizing? I have not done this earlier. Thanks, Chem55

Hi, I would like to know the butane gas solubility in Bitumen (Heavy oil). The bitumen has the Viscosity of 40,550 mPas and density 970.3 kg/m3. Operating Condition: The temperature is 19-20 deg cel and pressure is between 0.21 MPa and 0.23 MPa. I also have the Critical properties of bitumen...

Dear Lothar: I have tried according to your instruction; but it shows kind of erroe stating "port may not exist or another process may be using the port". I'm not sure what does than mean. Chem55

Yes, I have tried PDF995 and it is working great; but i need to convert in eps file. Do you have any idea, what is the best free software to convert AutoCad file to eps or jpg? Thanks, Chem55

Dear Lothar: I don't have problem to get the printout. I export the drawing to eps, and then I open the file by using the adobe illustrator or Ghostview. This eps file, which I open through adobe illustrator ot Ghodtview doesn't show any colour, It is just black and white drawing. Would you...

Dear Exxit: Would you pls elaborate your answer? I am a new user to AutoCad so may be thats the reason I coundn't get your answer.! One thing I forgot to mention that I am using AutoCad-2004. Thanks, Chem55

Hi.! I need to convert autocad file to eps file. It is a coloured drawing. To do so, I am exporting the autocad file to eps but the converted drawing is colourless. Would you pls suggest me what should I do? Thanks, Chem55

Hi TD2K & Ko99: I got the correct calculation from Chromalox technical article.! Thanks for your kind reply. Chem55

Hi: I have about 376 gallon(1421 lt) of water in a open cylindrical tank. I would like to use 6kw of heater and I want to increase 20 deg cel temperature. As per the formula, Kw = [gallons * T(rise)] / [325*Time(hrs)] I have calculated that it will take about 13hrs to temperature rise of 20...

Hi, I think this link would be helpful to you for typical U value. Just take a look at http://www.the-engineering-page.com/forms/he/typU.html Cheers..! Chem55

Hi, Could you pls suggest me how can I calculate pressure vessel thickness which is made of Plexiglas, if the pressure is 150 psi at 40deg cel? I found the formula from coulson & Richardson Vol.6 but I need Design stress of plexiglass at 40 deg cel to calculate the thickness. Can anyone...

Hi rmw: Yes, I will contact to Lance for this. Thanks, Chem55

Hi TD2K: I need to visualize the process inside the pressure vessel so thats the reason I'm looking for Transparent Pressure vessel. I also had Plexiglas in my mind but I’m afraid if I tight the bolts to fix the flanges, the Plexiglas will crack. I checked with vendors for thick clear PVC but...

Hi, Can anyone suggest me the vendor for transparent pressure vessel? The propane gas will be pressurized at 160psi pressure in the pressure vessel of 13inch (diameter)x 5ft long. Thanks, Chem55
