Hello All,
Another observation that I am rather curious about. Is there a reason why pressure gauges in particular tend to have fluctuated readings between calibrations? For example, the first calibration would have readings of 0,30, and 60 Pa. The next year it would be 0, 32, and 62 Pa. The...
I am trying to measure the efficiency of a spray nozzle by measuring the amount of air that "mixes" with water as it passes through the nozzle.
The experimental rig most likely will consist of an open port for free air to pass through. What would be the best way of monitoring the volume of
air...
Does anyone know how one can determine the pressure of gas inside a pressurised gas cylinder? We have a pressure regulator attached to a gas cylinder containing 9.5m3 of Nitrogen gas, with the inlet pressure showing around 140bar and the outlet at 5.5 bar. Is this possible?

Hi All,
I came across this term while looking at some documents pertaining to filters. It states:
"The acceptance criteria of clean bed pressure drop is <70kPa"
What is meant by this statement?
Thanks!

Hi All,
My site consists of 3 air compressors connected in parallel which are connected to an air receiver. The air compressors each have a maximum operating pressure and cut off pressure of 10 bar(g). All the equipment in the compressed air system are rated with a design pressure of 16bar(g)...
Hi all,
In your experiences, whats the most common way a temperature controller/probe would fail calibration? Assuming that the sensor could be any type of probe. (Thermocouple/RTD/thermistor)
Thanks!

Hi All,
I am trying to find out the flow rate that my air compressor has at different operating pressure. It has a maximum operating pressure of 10bar and a flow rate of 15.41m3/min at that pressure. If I were to operate 2 compressors at the same time to achieve a pressure of 16bar, how would I...
Hi All,
I am trying to find out the maximum membrane stress based on corroded thickness for a vertical air receiver. Is the membrane stress based on the Hoop Stress or Axial Stress?
Cheers
My current D orifice PSV has an inlet size of 20mm. If I were to attach a 8mm reducer to the inlet, what effects does it have on the PSV in terms of its set pressure, flow capacity etc?
Thanks in advance!
Does anybody know which standard talks about when a PSV is required? My plant has a 1300L desiccant dryer fitted with a PSV, while the other 190L dryer does not.
Hi everyone, I currently have an air receiver with a design pressure of 500kPa. It is connected to the same line as 3 air compressors which each has a flow rate of 18.54 m3/min. How would I go about calculating the required relief capacity of a PSV on the air receiver?
Thanks in advance!
As the title states above, what are the differences between these 2? I work at a manufacturing plant and the main switch board room in my building uses a rubber insulating mat spread across the floor. Whereas in the hazardous areas where combustible dust are present, ESD/anti-static (connected...
Hi everyone, I'm trying to find out how to calculate the vent area of a venting protection system, a dust collector with a burst vent to be more specific. The data I have of the dust material has a Kst Value of 350 and a maximum explosion overpressure of 5 bar (for example). How would I go about...
