Hello every body
I have a lot of .dwg colored files.
Is there any way to convert these dwg files to dwg black layer files. In the other hand i want to have one color (black) drawing not colored. I should say that i can convert one by one but i can not convert batch (for example 2000...
How does wellhead Shut-in pressure could be determined?
The pressure gauge installed on the X-Tree has been reached to 1200 psig after a long period when the X-Tree output valve is close and there is not any flow from the well.
Can we say that the wellhead shut-in pressure is 1200 psig or for...
In thermodynamic there is an important issue "STEADY STATE STEADY FLOW (SSSF) PROCESS".
MY QUESTION IS:
Is there any steady flow process that is not steady state? or is there any steady state process that is not steady flow?
what is the difference between steady state and steady flow process...
Hello every body
In oil and gas industry, some huge pumps or compressors is equipped with vibration switch to shut down the pump or compressors and others have not vibration switch.
It seems for huge pumps or compressors the installation a vibration switch is mandatory. My question is what is...
hello every body
In the oil and gas company there is a pressure vessel with name plate that shows the specification as follow:
design pressure (MAWP): 10 barg
design temperature: 100 C
length: 8 meter
I.D = 2.5 meter
material; carbon steel
and there is not any information about vacuum design...
What is the difference between depressuring and depressurizing?
For example API 521 somewhere says "depressuring" but somewhere says depressurizing! And also API 14G.
IS THER ANY SETTING TO SEE AUTOCAD FILES BLACK AND WHITE. I MEAN AT PRESENT WHEN I OPEN THE FILE, COLOUR LINES IS DEFAULT. I WANT TO BLACK AND WHITE AS A DEFAULT. THANK FOR ANY COMMENT.
choke valves installs on oil and gas wellheads to choke the flow. my question is choke valve function is same as converge nozzle or converge-diverge nozzle? can we reach to sonic velocity in chock valves? thanks for any comments.
We know: PV^^n= constant and n (polytropic coefficient) is also constant.
We know in centrifugal compressor n could be higher than 1 (isotherm ) and lower than gamma Cp/Cv (isentropic).
My question is what is the difference between for example n=1.2 and n=1.3?
For a centrifugal compressor...
Do anybody experience in oil and gas production wells with artificial gas lift that operate without any choke valve installation at upstream the well flowlines?
I have seen many oil and gas natural flow wells that all of them have choke valve after x-tree to control the flow and/or pressure of...
I'm postulating a scenario, perhaps this is a thermodynamic question! Any way I do need your help.
A fuel gas centrifugal compressor system consist as follow:
1. A gas supply reservoir with constant pressure of 10 barg that we can get maximum. 20,000 kg/h from it.
2. Centrifugal compressor...
It's a general question.
I was reading the design basis of the factory working there and I encountered the following Sentence :
... the design life of the pipeline is 25 years.
and also I know that corrosion inhibitor is injected to the pipeline continuously.
One of the my colleague says that...
It's a general question.
we know about the existence possibility of surge in centrifugal compressors. Is there any possibility of surge in positive displacement compressors? Is s there any possibility of surge in centrifugal pumps or positive displacement pumps?
Thanks in advance.
Hi everybody
Based on API 14c there is not necessary to apply/use PVRV for Atmospheric Vessels and API 14c explicitly indicate "... A second vent may be installed in lieu of the PVRV". in the other hand we can delete PVRV and instead of PVRV use another vent line! are we allowed do this.
I...
Hi everybody. Looking for thoughts/comments/guides.
base on API 2000 storage tanks are
"... tanks designed for operation at pressures from full vacuum through 103.4 kPa (ga) (15 psig)."
and based on api 14c:
atmospheric service has
"Operation at gauge pressures between 0.5 ounce psi (0.2 kPa)...
Is it necessary (mandatory) to use a firefighting systems (firefighting pumps and network for example hydrants, deluge,... on offshore oil and gas platforms? If so, which standard does it refer to? Actually I have tried to find what is the criteria to use firefighting systems and I couldn't find...
hello
How to increase (for example 10 percent) all row height in excel? or for example to increase 8 unit for each row height. I have a lot of rows with different height.
appreciate for any respond.
How can I convert multiple dwg files to pdf in windows 10. actually I can convert but the problem is dwg convert to pdf with coloured line and and text. I can not do monochorome multiple file convert.
Appreciate for respond.
