Compressors Practice Questions (Mechanical Engineering)
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids.A gas turbine, also called a combustion turbine, is a type of continuous combustion, internal combustion engine. Jet propulsion is the propulsion of an object in one direction, produced by ejecting a jet of fluid in the opposite direction. By Newton’s third law, the moving body is propelled in the opposite direction to the jet. Reaction engines operating on the principle of jet propulsion include the jet engine used for aircraft propulsion, the pump-jet used for marine propulsion, and the rocket engine and plasma thruster used for spacecraft propulsion. Biological systems include the propulsion mechanisms of certain marine animals such as cephalopods, sea hares, arthropods, and fish. These questions will give you basic idea for Examinations Preparation and/or interview on Compressors, gas turbines and Jet PropulsionPlease Note: These questions are for practice and understanding level of knowledge only. It is not necessary that these questions may or may not appear for examinations and/or interview questions.
