We need to install a control valve in our water filter test system. I see online a lot of formulas and calculators to determine the Cv. However, for it's calculation pressure drop is needed. Is it the max acceptable pressure drop of the valve or something else?
Secondly, the formula also...
I am trying to measure the no. of suspended particles in water using an inline particle counting sampler. The process setup looks as below:
To get a representative sample, the sampling process should be isokinetic. However, the sampler intake rate is fixed at 25 ml/min leading to an average...
The drawing below shows the future layout of our test system. For the position of the magnetic flow meter, I think if provided a few pipe diameters straight length upstream and downstream of the flow meter, it's location wouldn't affect too much on the flow measurement and ultimately the...
On our old water test rig, the SS316L pipelines dimensions seem a bit strange to me. It's an "antique" system so no documentation is available. So I measured the ID & OD using a caliper which came out to be:
OD = 52.32mm
ID = 49.56mm
Thickness (OD - ID) = 2.76mm
From the standard pipe schedule...
I want to modify an existing filter test setup with a 2 inch piping. The usual flow rates are 10 m3/hr and higher. To be able to test a different type of filter for which flow rates are quite low 1 -3 m3/hr on the same system I doubt that the pipes will remain full. The test fluid is water. Is...
I am designing a small mixing vessel and from my research the standard flanged and dished bottom seems to be the best choice for keeping particles in suspension. However, I am not able to find info/suggestions on choosing the dimensions of the standard flanged and dished bottom. The vessel in...
I am trying to determine the discharge pressure of a centrifugal pump in a closed water system.
The centrifugal pump sucks the water from the bottom of an open tank (open top and under atmospheric pressure) and circulates it through different small vessels before finally driving the water back...
Hi All,
For automatic control valve sizing, I need to determine the inlet and the outlet pressure. The setup is as follows:
From the main reservoir, water is pumped through a centrifugal pump to another vessel. In between the centrifugal pump and the vessel there is a valve that can be used to...
Hello guys :) I would like to ask a question regarding dirty water & centrifugal pumps. I have recently started working in filtration company and we test the filtration efficiency of our filters using water mixed with test dust. The test dust has particle size range from 1 to 100 micron. The...
