2. DEVELOPMENT OF IMPULSE
MOMENTUM PRINCIPLE
 This concept is important in flow problems
involving determination of forces.
 Forces occur whenever the velocity of a stream
of fluid is changed in either direction or
magnitude.
 By law of action and reaction, an equal and
opposite force is exerted by the fluid upon the
body producing the change.
 Principles of impulse momentum will be
developed for to understand the better
understanding of the machines like pumps and
turbines.
