Flow does not like the pressure gradient it sees going into the compressor and is therefore, more likely to separate (causing flow separation). Therefore, a more subtle increase in pressure through each stage is needed in the compressor.
The turbine does not see this problem.

How many stages of compresion on a j79 gas turbine engine?
The J79 gas turbine engine features a single-stage fan and a nine-stage axial compressor, which together provide efficient air compression before combustion. This design allows the engine to achieve high thrust levels and operational efficiency. Overall, the engine has a total of nine stages of compression in the axial compressor.
What is multistage reciprocating air compressor?
A multistage reciprocating air compressor is a compressor that compresses air in a number of stages. A multi-stage reciprocating air compressor may contain 2 or many cylinders, like low pressure, medium pressure and high pressure cylinders.
How many parts are in a jet engine?
A jet engine typically consists of several key components, generally categorized into four main sections: the intake, compressor, combustion chamber, and turbine. Within these sections, there are numerous individual parts, including fan blades, compressor stages, fuel injectors, and nozzle assemblies. The exact number of parts can vary significantly depending on the engine design and model, but a modern commercial jet engine may have thousands of individual components.
How does an extraction turbine work?
An extraction turbine is a type of steam turbine that operates by extracting a portion of the steam at intermediate pressure from the turbine for use in heating or other processes. As steam enters the turbine, it passes through various stages, converting thermal energy into mechanical energy to drive the turbine blades. The extracted steam is typically at a lower pressure and temperature, which makes it suitable for applications like district heating or process heating in industrial settings. The remaining steam continues through the turbine to generate additional power before being condensed and returned to the boiler system.
Why flywheel is used in reciprocating compressor not in centrifugal compressor?
Flywheel prevents fluctuation in the speed of the motor as a result of load fluctuation. It stores the energy and dissipates it to the compressor for prolonged period. So the load fluctuation which is high during compression stage and low during other stages during a cycle in reciprocating compressor gets nullified. On the other hand, centrifugal compressor continiously compresses the gas and does not have load fluctuations, hence flywheel is not required.

How do you find the number of stages in the compressor?
To determine the number of stages in a compressor, you need to consider factors such as the desired pressure ratio, efficiency requirements, and the size of the compressor. Multiple stages are typically used to achieve higher pressure ratios or when operating conditions require greater efficiency. Consult the compressor manufacturer's specifications or consult with a mechanical engineer for specific guidance.
What is high pressure compressor in turbine engine?
In an axial flow turbo fan engine there are two compressors. The first compressor is the low pressure compressor or it can also be referred to as the fan and is the first rotating assembly in the engine located aft of the engine inlet. The second rotating assembly located aft of the low pressure compressor or fan is the high pressure compressor. The basic difference between the low and high pressure assemblies is the amount of air pressure they generate. Low pressure compressors usually have a small number of stages and fewer and larger blades. Whereas the high pressure section has more stages and smaller blades. As the air passes through each stage of the compressors it is squeezed thus the pressure and temperature increase. When the air flow exits the high pressure compressor it is at its highest temperature and pressure generated by the cold section (compressor section) of the engine. Hot section/combustion section is another matter. Keep in mind that there are numerous turbo fan/turbine engines and each one probably will be configured differently as far as the number of stages and blades in each compressor section.
What is the control stage in steam turbines?
The control stages are the stages at which steam is admitted to or extracted from the turbine. These "control" the output of the turbine.
How many stages of steam turbine rotor?
It depends upon megawatt of turbine & design of blades.
How do you decide number of stages for a steam turbine?
It is generally based on the Type of rotor ( Impulse/ curtis) and the enthalpy drop per stage.
What is a steam turbine diaphragm?
Steam turbine is comprising of stages, number and size of the stages depands upon the break horse power of the turbine. The stage has set of moving and fixed blades. The moving blades are attached to the rotor while the stationary blades is called Diaphragm. The diaphragm guides the steam to glide over the moving blades for producing rotary motion.

Why the gas turbine needs 3 bucket stages only in 110MW TURBINE?
The 3 bucket stages in a 110MW gas turbine are designed to efficiently extract energy from the high-pressure hot gas produced by combustion. By using 3 stages, the turbine can effectively expand the gas across multiple stages, thereby maximizing energy extraction and overall efficiency within the power plant. Additionally, the design may also optimize the velocity and pressure of the gas flow to ensure proper turbine performance at the specified power output level.

Where is bleed valve located on engine?
The bleed valve on an engine is typically located on the compressor section, often near the turbine or in the high-pressure compressor stages. Its primary function is to regulate airflow and prevent compressor stall by venting excess air. In aircraft engines, this valve is crucial for managing engine performance during various phases of flight, particularly during takeoff and landing. The exact position can vary depending on the engine design and manufacturer.
What are stages in steam turbine?
one stage is the combination of one moving blade and fixed blade.
