For a perfect incompressible liquid, flowing in a continuous stream, the total energy of a particle remains the same, while the particle moves from one point to another. This statement is called

A.	continuity equation	B.	Bernoulli's equation
C.	Pascal's law	D.	Archimede's principle

113.

The Bernoulli's equation is based on the assumption that

C.	no force except gravity acts on the fluid	D.	all of the above

114.
