Mechanical Engineering :: Compressors, Gas Turbines and Jet Engines
- Isothermal compression efficiency, even when running at high speed, can be approached by using
- A rotary compressor is driven by an
- Ramjet engine
- The blades of gas turbine are made of
- The axial flow compressor is preferred in aircraft gas turbines because of
- In the aircraft propellers
- For a two stage reciprocating compressor, compression from p₁ to p₃ is with perfect intercooling and no pressure losses. If compression in both the cylinders follows the same polytropic process and the atmospheric pressure is pa, then the intermediate pressure p₂ is given by
- If V, U and Vr represent the absolute velocity of fluid, velocity of blade, and relative velocity of fluid, and suffix ‘I’ and ‘o’ stand for entry and exit conditions, then in a rotary machine whose degree of reaction is unity
- The air is delivered ________ in one revolution in case of a three lobbed rotor.
