How do you calculate Time to Steady State?

AI Thread Summary
Calculating time to steady rate involves understanding the concept of steady state, which refers to a condition where variables remain constant over time. The discussion emphasizes that without a clear context, it's challenging to provide a precise answer. It highlights that achieving a true steady state is mathematically impossible; one can only approach it asymptotically. The conversation also points out the importance of defining what "close enough" means in practical terms, as the distance from steady state typically decreases exponentially. For further clarification, seeking resources that explain these concepts in detail is recommended.

Hey,

Can someone explain to me how you calculate time to steady rate? Or provide a website that explains it? Not having much luck :(

Thanks!

What steady state are you talking about? It is impossible to comment without knowing what the context is.
 
No matter what the context is, if you don't start from the steady state you will never exactly reach it - you can get as close as you want, but you won't get there, ever. This is just math - in most cases the distance from the steady state will diminish exponentially.

So you have to start defining how close is close enough.

https://www.nhs.uk/mental-health/conditions/body-dysmorphia/ Most people have some mild apprehension about their body, such as one thinks their nose is too big, hair too straight or curvy.

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...

Thread 'Warning of new opiod drug (nitazene) on the streets: Question re strength...'

Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
