Bernoulli's principle

when you blow in a bag from outside the bag, the bag inflates quicker than if you put your lips against the bag and blow it up like a balloon.

because increase in speed, results in a decrease in pressure. so surrounding air is sucked in.

this applies to fluids and ventilation.

  • uses Bernoulli’s principle to create a low pressure zone under the cooker hood, which results in the air under the hood being sucked outside.
