I would like to use the equations for a screw pump, but i am unable to find any online. I had figured that everything would be the same because all i did was eliminiate the screw shaft and put the fins on the wall of the casing. If you know where i can get some calculations i would apreiciated it.
Does anyone know where i can get the calculations for sizing an inverted screw pump. Inverted being that there is no screw but the fins art attached to the inside of a pipe and the pipe is rotating. I am moving any where from 150 to 400 lbs of dry powder per minute, depending on the amount of...
Our plant shares resources with another. We receive 400# super heated steam and use that for some processes. We also have let down stations where we use 280# and 180# steam. the plant is over 60 years old and we are in the process of redesigning our steam and condensate lines for better efficiency.
Apparently it was, but not intended to be. I knew that there would be some due to temperature change, but apparently there is not enough to make a difference. I guess that is why i could not find any such calculations.
We have 400, 280, and 180 lines. Thank you for your help.
Another engineer working on this has forwarded me this answering my question.
The steam at 400 psig is superheated steam, meaning instead of being at the saturation temperature, 448.16 F, it is at 600F. Therefore it has ~ 152...
If I have 400# and 180# steam, how can I calculate the pressure of the condensate that is being produced after the steam is used on the various tanks and equipment? I am being asked by one of my process engineers to find this.
Any help would be greatly appreciated.
Thanks
