That's the art of the design. Once you start to flow you want the valve to open fully with a very small increase in pressure. There's a lot of effort goes into the design.
Blowdown percent is normally in the range 7 to 10%. So difference in force is not that big.
Is there a gap under the TX?
Could you not just create a tri angular frame and just use the blocking as extra weight?
Or use that to fix the two blocks together?
Probably not surprising when all the forces are also being experienced by the blocks as well as the item ( large transformer?)
Have you considered screw anchors or burying those blocks?
Or just ignoring seismic as an unlikely / rare event over a one year period?
Is the pump designed for 60 htz operation? Power goes up by a factor of pump speed ^3. So this is 70% more power at 60 htz than 50 htz. Does that have an impact maybe?
Well contrary to innovative pumps (welcome!), PD pumps are the only ones I am aware of for multiphase pumping.
Progressive cavity are ok if the vendor says so.
Each pump can work independently or together, but both need to be rated to the same discharge pressure.
Pressure though is driven not...
There is a user here called "latexman" who is the most knowledgeable one I know about things like this.
Try sending him a message and ask him to chip in?
What sort of calculation are you after?
Looking at what you have ( any links you can share), look like vendor certified equipment tbh.
Vector techlok are the only type I see for high pressure stuff.
You're at the top end for size and pressure for these types of clamps.
Personally I think...
If this is a test set-up where you can fix the location of the input flow and then pipe the output to other test elements, I would be very tempted by either a Coriolis meter or some sort of PD meter tbh. or just pump a defined volume and time how long it takes (simpler the better)
I don't know...
George,
I the pipe itself can syphon back, i.e. all the water int he pipe downstream the high point could flow back, though in reality air will get in there to destroy the sysphon.
Here's some papers of gravity flow..
What Imeant previously is that your pressure at the high point could very...
Negative head red line is not possible.
Red dashed is better but you'll have slack line/ unstable flow
Blue line is better, but if you don't have a valve adding back pressure then that last 50m will be leaning towards slack line flow as well.
The margins though are really low so it might...
Yup.
When you're dealing with unstable flow, unstable things happen.
Letting it drain from the bottom is not good, but if Katmar is correct and you're only just at atmospheric pressure at the high point when pumping, an air valve could let in sighs of air which died the same thing.
Well temperature range at the very least. Your "high temperature" might not be mine and vice versa.
When you're talking to vendors then the first thing they'll ask is for properties of the fluid to see if works with their meter, plus velocity, density etc

Looks to me to be very vendor dependant, but the internal flow path of a top suction pump usually has a 90 degree element to it so they seem to be less picky about the 5D.
So you need to see what the pump...
From what I can see the hydraulic system for the MAX is basically unchanged from the NG.
So you really don't want to lose your no 2 engine by the look of it.... There is an electric pump but it is lower capacity.
There are some elements of standby and crossover, but I think to would take you a...
Ok, that makes it clearer. From your OP I thought you were trying to do all this yourself...
So is this re gassified LNG? If so it will be virtually pure methane and VERY dry. You will need to tell all the vendors, valve suppliers etc about that as seals and elastomers can dry out or lose...
