Which of the following represents conservation laws ?

a) equation of continuity

b) Bernoulli's Theorem

c) magnus effect

d) Torricelli's Theorem

• The law of conservation of mass in fluid dynamics is demonstrated by the equation of continuity. Additionally, the density will remain constant for steady flow if the fluid is incompressible.
• According to Bernoulli's principle, The gravitational potential energy of elevation, the energy related to fluid pressure, and the kinetic energy of the fluid motion make up the entire mechanical energy of a flowing fluid and are all constant.
• The force applied to a quickly rotating cylinder or sphere travelling through air or another fluid at an angle to its spin axis according to Bernoulli's relation is known as the "magnus force." When struck or thrown with spin, this force causes balls to veer to one side. This effect is called Magnus effect.
• Torricelli's Theorem - The square root of the vertical distance and the speed of a liquid pouring out of a tank opening under the influence of gravity, v, are both proportionate.

Hence the correct answer is a, b are correct.
