State Bernoulli is relation for a liquid in motion and describe some of its applications.
Answers
Answer:
Bernoulli's Theorem:
According to Bernoulli's theorem, the sum of the energies possessed by a flowing ideal liquid at a point is constant provided that the liquid is incompressible and non-viseous and flow in streamline.
Applications of Bernoulli’s Theorem
(a) Blowing off roofs during wind storm
In olden days, the roofs of the huts or houses were designed with a slope as shown in Figure.7.34. One important scientific reason is that as per the Bernoulli’s principle, it will be safeguarded except roof during storm or cyclone.
(b) Aerofoil lift
The wings of an airplane (aerofoil) are so designed that its upper surface is more curved than the lower surface and the front edge is broader than the real edge. As the aircraft moves, the air moves faster above the aerofoil than at the bottom
