Question

Bernoulli's equation for steady, non-viscous, incompressible flow expresses the

• A. conservation of linear momentum
• B. conservation of angular momentum
• C. conservation of energy
• D. conservation of mass

Answer 1

Answer: (C)

conservation of energy

For ideal fluid and steady , non viscous we can apply energy conservation in these type of fluid, which is given by Bernouel's equation

$P+\rho gh+\frac{1}{2}\rho v^2$

$P=$Pressure

$g=$ acceleration due to gravity

$h=$height above sea level

$v=$velocity

$\rho =$density

Bernoulli's principle can be derived from the principle of conservation of energy.
