The spray bottles used as window or household cleaner or perfume spray works on: __________?
AStoke’s Law
BPascal’s Law
CCapillary action
DBernoulli’s Principle
Correct answer
D. Bernoulli’s Principle
Explanation
When we press the top of bottle the pressure at top of the bottle decreases and hence, the velocity of liquid flow increases. Bernoulli’s Principle states that an increase in the speed of a fluid produces a decrease in pressure and that a decrease in the speed of a fluid produces an increase in pressure. The principle states that the total energy of a moving fluid remains constant at all times.
