Dear all,
I am looking for manufacturers of transparent pipes for "high pressure" applications.
Typically up to max. 30 bar.
Flow typically 100 kg/h.
Typically 20 mm to 40 mm (millimeter) diameter for the pipes.
We have a non-transparent, viscous product containing hard crystalline salts, so...
Dear all,
Does anyone has a simple (DYNAMIC) model (massbalance) of a gas - liquid mixer?
So, liquid stream and gas stream as input and two-phase mix-flow as output.
Help is appreciated,
CARF

Hi,
This link with a static evaporator model may help for basic understanding.

I can sent you a report and some Simulink files to make a first start for a dynamic model. Simulink is a product from the MathWorks (see other forums).

Hi all,
I made an overview of "all" equations required for simple fluid flow calcualtions in round pipes. Laminar and turbulent flow, Reynolds, etc.

There's also a FREE fluid flow calculator based on these equations.
Or a direct link to a web...
Dear all,
Here are "all" equations, including the iterative algorithm of
Colebrook-White.

A freeware fluid flow calculator based on these equations can be downloaded on bottom of the webpage.
Or a direct web application:

Hope this helps to solve your problem,

Dear all,
Does anyone of you has practical experience with the systems from Artesis?
The unique Artesis intelligent predictive maintenance system is suitable for most electric motor-driven equipment, as well as generators. It diagnoses a very wide range of electrical and mechanical faults...
Dear all,
I found this sensor to measure Humidity in Hydrogen Peroxide (H2O2) Atmospheres (for sterilization purposes).
The use of hydrogen peroxide (H2O2) as a sterilising agent in healthcare and production processes is extremely important to health and safety and has been growing in recent...
Dear Dave,
That's a very good question, I realised there is no such thing as in-line density of a powder. I depends on the ratio of the particles to the transport medium.
The off-line measurement gives 30 kg/m3, but that also depends on the bulk stacking. If we transport the powder it may...
Dear all,
Does anyone of you know manufacturers of in-line measuring systems for density of powders? The powders we produce typically have a density of 30 kg/m3. We want to measure (and control) in-line density.
Many thanks,
CARF
Dear all,
We encounter increasingly vibrations over a period of 12 hours on hour decanter centrifuge. Probably the machine gets fould because after a hot water flush (cleaning) the oscillations dissapear. Does anybody has experience with this and how to solve it? Typically we want to run much...
Dear all,
We are thinking of applying a frequency inverter to a motor wich controls the liquid level in a vacuum condenser (through a centrifugal pump).
Has anybody experience with VSD-drive level control in an industrial vapour condenser?
Many thanks for sharing knowledge,
CARF
