Omarat,
It could be that the water temperature increases (different physical properties) and additionally the pump, nozzle and control valeve increase in temperature(different system characteristics.
Your pump will put heat into the liquid. Slowly this will heat up the pump and parts...

Do not know whether you want just theoretical or more practical suggestions. Herewith only two (2) theoretical suggestions:
(1) As the medium consists of non-condensables and condensables, you can assume near the pipe wall an area (distance) where condensables will deplete. In this...
Milkboy the configuration you describe can be used for e.g.:
(a) as described by JJPellin to prevent abrasives to come between the seal faces;
(b) to cool/lubricate the seal faces; and
(c) to prevent air ingress in seal cavity with negative pressure.

However the answer from unclesyd is a very accurate answer to your question, I would like to draw you attention to another very important point to achieve a tight connection, being the bolt closing torques.
If the agitator is hanging on the nozzle and/or causes substantial dynamical...
Chief,
If you want pump curves on the Magmum XP just phone the manufacturer or their local assistance office, which can be found on their website, and ask them for the pump curves of your model.
I do not know the exact requirements for the service intended for this pump. Has this pump for...
bnmorgan,
If you are just looking for a guide on the design of the venturi, you could try the geometry of a natural draft cooling tower as a starting point.
bnmorgan,
It appears you do not get a reply on your request by people experienced on this subject. You are speaking about a small fan placed in warm rising air accellerated by a venturi boundary. The driving forces involved are small, which will lead to large geometries to achieve some real...
Vic123,
Just to give you an idea of the differences:
Nett positive suction pressure required = Atmospheric pressure - vapor pressure - liquid friction pressure loss in pump - liquid accellerations in pump.
Density of liquid
Nett positive suction pressure required = gravity constant x density x...

If the recycle flow change occurs only, when there is a pressure surge (drop) in the scrubber, the phenomen should be triggering the flow reduction.
Having the pump operating on a flow substantially below the BEP and on reduced rotational speed, it could be that the pump is...
Technopriest,
The replies given are, according to my view, all quite right, but let me give my view on your questions, assuming the static discharges by the product are continously (zone 20) capable to cause an explosion in the vessel:
1) Yes, if static discharges from the product are capable to...
Snoop02,
I'm afraid that your NoBo is not really wrong in his statements. I do not know in which part of the world you are located, not whether you are a manufacturer of pressurized equipment, or material to be used for pressurized equipment to be covered by the PED.
You will probably know...
Maybe it is helpfull to give a website with a brief summary, and the full text, of the Pressure Equipment Directive (PED):
http://ped.eurodyn.com/
The full text can be encountered entering the link "Pressure Equipment Directive" on the left side of the website.
Note that the PED serves only...
13392017, it is difficult to answer your question in full. Quark can be right, pending on the application and service of the pressure testing unit.
Pending on the location where the unit will be sold and/or put into service, analysis of HAZOP, safety and risks should be performed considering...
If I understand the question correctly, this is about a really high pressure application (15 000 psi), where the pump has to be freed (isolated) from the discharge system leaving the discharge system pressurized and the pump without pressure. Assuming you are talking about a positive...
