Which theorem law can explain the working principle of sprayer?
- a.Stoke's law
- b.Bernoulli's theorem
- c.Jurin's law
- d.Virial theorem
Answer: (B) Bernoulli's theorem
In a sprayer, fast-moving air over the top of a tube lowers the pressure there (Bernoulli's theorem), so the liquid is pushed up the tube and broken into droplets. Stokes' law concerns viscous drag, Jurin's law capillary rise, and the virial theorem orbital or molecular energies.
