Impact of Jets and Jet Propulsion topics include: Exerted force by a jet on a vanes series, exerted force by a fluid jet in stationary flat inclined and curved plate.

In fluid mechanics, the theory of impact of jets describes the force generated when a jet of fluid hits a surface. The theory states that the force of the jet is equal to the fluid's mass flow rate multiplied by its velocity. 

When a jet of water strikes a surface, its velocity and momentum change. The force exerted by the surface on the jet can be calculated using Newton's Second Law. This force is called a dynamic force. 
Jet propulsion is the propulsion of an object in one direction by ejecting a jet of fluid in the opposite direction. This is based on Newton's third law. 

Some examples of reaction engines that use jet propulsion include:
Jet engines for aircraft propulsion
Pump-jets for marine propulsion
Rocket engines and plasma thrusters for spacecraft propulsion 

Water jets are also used in power plants to clean boilers, re-heaters, cyclones, and scrubbers. In chemical and plastic plants, water jets are used for tank and reactor cleaning, and for pipe and tube cleaning.
