Bernoulli Bag (Capacity Of Lungs)
- SKU: PH 1021 T
Working Principle – Bernoulli’s law
The challenge: How many breaths of air will it take you to fill a plastic bag thatâs 8â (2 m) long and 10â (25 cm) in diameter? Depending on your size, it may be anywhere from 10 to 50 breaths of air, that is if you have the stamina for it. However, with a little practice and some knowledge of how to use air pressure differences, youâll be able to inflate the same bag with only one breath! When you can do that, thereâs a whole lot more you can do with the bag, too.
- A simple to perform experiment gives students a glimpse into the capacity of lungs in a human body.
- This manipulative is helpful in understanding the Bernoulli’s law, as per which it is observed that a stream of moving air is surrounded by an area of low atmospheric pressure
- Correlation between theory and practical becomes easier
