The correct answer is C. energy.
Bernoulli’s principle is a statement about the conservation of energy. It states that for an inviscid, incompressible flow, an increase in the speed of the fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid’s potential energy.
The principle can be derived from the principle of conservation of energy. Consider a fluid flowing through a pipe. The fluid has kinetic energy due to its motion, and it also has potential energy due to its position. As the fluid flows through the pipe, its kinetic energy increases. This can only happen if the fluid’s potential energy decreases. The decrease in potential energy is manifested as a decrease in the fluid’s pressure.
Bernoulli’s principle is a very important principle in fluid dynamics. It is used to explain a wide variety of phenomena, such as the lift on an airplane wing and the Bernoulli effect.
The other options are incorrect.
- Option A is incorrect because Bernoulli’s principle does not deal with the conservation of mass.
- Option B is incorrect because Bernoulli’s principle does not deal with the conservation of momentum.
- Option D is incorrect because Bernoulli’s principle does not deal with the conservation of work.
