In stream line flow of liquid, the total energy of liquid is constant at
a)	all points	b)	inner points	c)	outer points	d)	None of these

(a)

According to Bernoulli’s theorem when an in compressible and non-viscous (liquid) or gas flows in stream-lined motion from one place to another, then at every point of its path the total energy per unit volume (pressure energy + kinetic energy +potential energy) is a constant.

Hence, in stream line flow of liquid, the total energy of liquid is constant at all points.
