Choose the focus of using momentum equation
determine the forces associated with fluid flow
determine the pressure associated with fluid flow
determine the velocity of fluid flow
Newton’s law are
the relations between motions of bodies and the forces acting on them
the acceleration of a body is proportional to the net force acting on it and is inversely proportional to its mass.
the acceleration of a body is proportional to the net velocity acting on it and is inversely proportional to its area
Newton’s second law is expressed as
F=mV
F=ma
F=mg
F=ma can also be expressed as
= (dmV)/dt
=m(dV/dt)
= ρQ(V2−V1)
m.(V2−V1)
