Uncertainty in mass measurement
Web1 Jun 2024 · Calculating mass balances to monitor the performance of all units is important. For some of these units, like the fluidized catalytic cracker and the Coker, achieving the ±1-2% target for mass balancing can be difficult. For example, due to the challenges with measuring the Coke product, the Coker can often have an imbalance of ±5%. WebThe proportion of people aged 18 years and over smoking cigarettes in the UK is estimated to have changed from 20.2% in 2011 to 14.7% in 2024.

WebUncertainties express the confidence to which the measurement can be taken Random Errors When you are reading an instrument and estimate the final digit, there is an equal chance that you may read it slightly too high or slightly too low This is a random error Random errors are can be affected by: How easily the instrument or scale is to read WebUncertainties in Measurement What is uncertainty When you are making a measurement, there is always some degree of uncertainty in your result. A person who says they are 1.94 m tall is unlikely to be exactly that height and could be up to half a centimetre taller or smaller. We say their height is 1.940 ± 0.005 m.
Web29 Sep 2011 · Two experimental techniques determine the mass of an object to be $11\pm 1\, \mathrm{kg}$ and $10\pm 2\, \mathrm{kg}$. ... It would be highly unreasonable to obtain the uncertainty of the average of the measurements to be greater than the uncertainty of any one measurement (√5/2 > 1). After all, what's the point in taking averages if it just ...
