Analysis Of Finite Control Volumes - the application of momentum theorem

We'll see the application of momentum theorem in some practical cases of inertial and non-inertial control volumes.

Inertial Control Volumes 
Applications of momentum theorem for an inertial control volume are described with reference to three distinct types of practical problems, namely

• Forces acting due to internal flows through expanding or reducing pipe bends.
• Forces on stationary and moving vanes due to impingement of fluid jets.
• Jet propulsion of ship and aircraft moving with uniform velocity.

Non-inertial Control Volume 
A good example of non-inertial control volume is a rocket engine which works on the principle of jet propulsion.

We shalll discuss each example seperately in the following slides.
