1. what is gas turbine describe it.

Answer:

A gas turbine is a combustion engine that can convert natural gas or other liquid fuels to mechanical energy. This energy then drives a generator that produces electrical energy.

2. it is used in gas turbines and jet engines

Answer:

axial compressors

Explanation:

Modern large turbojet and turbofan engines usually use in axail compressors.

3. 1. Explain the advantages of Gas Turbine

Answer:

1. They are small in size, weigh less and have low initial cost per unit output.

2.They are easy to install within short periods.

3.They are quick-starting and smooth running.

4.They offer flexibility by supplying electricity for power generation as well as by supplying compressed air for process needs.

5.They are capable of using a range of liquid and gaseous fuels including synthetic fuels.

6.They are subjected (put) to fewer environmental restrictions than other prime movers.

Explanation:

hope it's help

5. At what stage in a turbine engine are gas pressures the greatest

Answer:

From stage 1 (row 1 of the compressor blade-vane sets) leading towards the burner, air pressure increases and air temperature increases. So, for this UUNBURNED air, the highest “air pressure” is right before the entrance to the burners.

Inside the burners, high pressure fuel is injected (usually either jet fuel (aircraft and Navy ships) or natural gas (industrial and electric power turbines) , mixed, and then burned. The now extremely hot, extremely high pressure exhaust gases then leave the burner and are directed right into the first stage of the exhaust turbine - which is where power is extracted in subsequent exhaust stages until it leaves the gas turbine exhaust.

So the highest “gas pressure” (and highest gas temperature) is right at the top of the burner, just before the gas enters the first row of the exhaust turbine blades.

6. An ideal gas mixture has a volumetric composition of 25% N2, 50% O2, and 25% CO2. The mixture flows through an insulated turbine at a rate of 12 kg/s. The mixture enters the turbine at 2 MPa and 500°C, and exits the turbine at 300 kPa. The turbine has an isentropic efficiency of 0.85. Assuming that the changes in kinetic and potential energy are negligible, and that the mixture has constant specific heats (evaluated at 600 K), determine the power produced by the turbine and the entropy generation rate for the process.

See the attached images.

7. reflection how this kind of gas turbine engine works?

Answer:

A gas turbine engine operates by compressing air to high pressure, combusting fuel in the air stream which increases pressure and temperature, then expanding the high-pressure exhaust gases through a turbine to produce work. Some or all of the work produced by the turbine is used to power the compressor.

Fan, compressor isentropic efficiency: 0.9

Turbine inlet temperature: 1500 K

Combustion chamber pressure loss: 1.3 bar

9. In air-standard analysis of a gas turbine, the temperature rise that would be brought about by combustion is accomplished by heat transfer from an external source. as such, air-standard analyses are of little value when studying combustion gas turbine performance.

Answer:

study hard ambition success

10. How is thrust generated in a gas turbine engine?

Answer:

In a jet engine the turbine is designed to provide just enough output to drive the compressor and auxiliary devices. The stream of gas then leaves the turbine at an intermediate pressure (above local atmospheric pressure) and is fed through a nozzle to produce thrust.

Explanation:

11. difference of turbine and tesla turbine

Answer:

oni chan your so kawaiii

Answer:

The main difference between the Tesla turbine and the turbines used nowadays to propel jet planes, for example, is that instead of using curved blades like those of a windmill, it generates movement through smooth and parallel disks placed evenly across a shaft, like CD's placed along a pole.

12. Make a comparison in between single-shaft and split-shaft gas turbine engine in terms of their construction and operating principle.

Answer:

If the load speed is constant, as in the case of an electric generator, a single-shaft unit is often specified; an engine specifically designed for electric power generation would make use of a single-shaft configuration.

An alternative, however, is the use of a two-shaft engine. If the load needs to be driven with varying speeds (compressors, pumps), two-shaft engines are advantageous.

Explanation:

single-shaft

In single-shaft turbines, controls speed by regulating the gas control valve or the liquid fuel valve.
