Question

In steam 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

Answer 1

Answer : A) All Points

Refer Bernoulli's theorem :  the total mechanical energy of the flowing fluid, comprising of the energy associated with fluid pressure, the gravitational potential energy and the kinetic energy for the fluid motion remains constant. 

Bernoulli’s theorem is the principle of energy conservation for ideal fluids in streamline flow.

Mathematical reference : 

	=	density of the fluid
	=	acceleration due to gravity
	=	pressure at height 1
	=	velocity at elevation 1
	=	height of elevation 1
	=	pressure at elevation 2
	=	velocity at elevation 2
	=	height at elevation 2

Answer 2

A} All points
