AEnergy
Correct Answer
BMomentum
CAngular momentum
DMass

Solution

Bernoulli's equation : $$ \bigg[ P + \rho gh + \dfrac{1}{2}\rho v^2\bigg] = constant$$
where $$'P' $$ is the pressure energy
$$'\rho gh' $$ is the potential energy per unit volume
$$ \dfrac{1}{2}\rho v^2 $$ is the kinetic energy per unit volume

Thus Bernoulli'e equation implies that the sum of energy is constant and hence is the conservation of energy.
