So essentially just 10 centimetres again divided by 2.0 seconds. This would be Delta y over delta T There isn't any why component at T equals zero. And then it would be for the average velocity in the UAE direction. This is giving us 5.0 centimeters for a second. So 10 centimeters divided by 2.0 seconds.

I had plus 10.0 centimeters j a happ and so we can then say that, uh, in the the average velocity in the ex direction would be equal to 14 minus four. Then our hat is equaling 4.0 centimeters. And so, at the time equaling zero, we know that. We know that the position vector in unit vector form would be 4.0 centimeters plus 2.5 centimeters per second squared times, t squared times I hat and this would be plus 5.0 centimeters per second times T J hat. And so this is going to be equal to rather this would be the key equation that we're using. The instruments operate in a wide dynamic range enabling the use of the same instrument for measurements before and the filter.So here we're going to use the definition for the average velocity, this would be the average velocity vector would be equal to the position vector that time to minus of position vector at time. Our instruments additionally enable gravimetric and chemical analysis of size classified particles with cascade impactors, PM10 вЂ“ 2.5 вЂ“ 1.0 measurements and real-time particle size distribution measurements. Our measurement solutions provide options for real-time monitoring of particulate mass, number, or the lung-deposited surface area (LDSA) of the particles, and for total concentration and particle size distribution measurements.

Our particle measurement solutions have been successfully used in filter efficiency testing and research for over 25 years and today, our instruments are used globally by thousands of customers both in research and industry to measure different properties of airborne particles <10 Вµm.ДekatiВ® measurement instruments provide more detailed information than what filtration standards (EN 149, EN 13274, EN 14683) require.

How to measure particle filtration efficiencyДekatiВ® measurement solutions for particle filtration efficiency (PFE) research and testing include both real-time instruments and gravimetric cascade impactors for particle size distribution and concentration measurements. Because of this size dependence, it is important to evaluate the filtration efficiency separately for different sized particle to properly understand the operation of the filter material. The amount of removed particles by the filter depends on the filter properties and is typically highly dependent on particle size. Typically, the effectiveness of the filter is described with a filtration efficiency value, which is the efficiency of the filter to remove particles from the air flow in percentage (0вЂ“100 %). The removal of the particles by the filter happens via different mechanism including interception, impaction, diffusion and electrostatic attraction. Different types of filters such as fiber filters, membrane filters and fabric filters can be used to remove particles from air flow.
