Artisi, agreed …..but in this case the level in tank 1 will drop faster i.e. the head will decreases faster . hence, the flow rate will decreases with time. It’s a dynamic system !
We may end up empting the two tanks at the same time. !!
katmar,BigInch-thank you.
No, it wasn't a homework. it was a discussion at work. the argument maily was the "head", some say's that in both tanks it shold be 10 m !!!?
I had a long argument on this with my friends( Eng's) therefore, I decided to post it here to get your opinion:
Two Tanks have the same capacity and are at the same height. They are at 10m elevation. Both are open to atmosphere. They contain water. From each an 8” pipe comes down the tank to...
Hi,
manly there are 3 mothods:
Method 1: Average (Default) Emissions Factor Method;
Method 2: Correlation Equation Method; and,
Method 3: Screening Value Range Method.
if you use google you will find intresting things.
Zdas04,
It’s seems that we are not in the same page, I’m talking about the design not the work . I’m designing a caustic dosing system, do I need to provide DBB for the pump ( head=70ft).
Thanks Zdas04 for the replay, I gone through attached doc. But still not clear to me what determining the need for DBB. Is the pressure or the fluid type.
I have question : when is the double block and bleed valve is must or required, what is the reference API, OSHA ..etc?
I know that for more than 10 bar it’s required but what about corrosive chemical handling for less than 10 Bar is it required a double block and bleed valve?
Hi all,
I got an engineering request to study the possibility to build a bypass around an ESD valve for maintenance purpose. Is it acceptable? I haven’t seen a bypass around ESD ! what is API or ASME reference in this case. ?
