Last week I worked error propagation for a pitot measurement to flow rate conversion.
Because it's a measurement, there is a natural level of precision that we can only estimate that depends on the precision level of each of our measuring points (our tools). Yet, we (maybe just I) often overlooked the concept of measurement error. In this tool (below), I've incorporated the error propagation to suggest a range for the result instead of what we typically express as a near-certain test measurement. So, now, you can convert a pitot pressure into a flow rate and immediately get the error tolerance based on the tools you've used and measurements you've taken. Hardly any additional work. While it may sound trivial, knowing what amount of tolerance we are actually achieving in a test measurement could be the difference between a test pass or test failure - especially in regards to fire pump testing. Check out the tool below, and let me know what you think! It has an IP and SI version built in (I'm finally catching on).
If you're a member of MeyerFire University this will be added to the iOS and Android app automatically.
Thanks and have a great rest of your week! - Joe
