What is the self-sustaining speed of gas turbine?
self sustaining speed is output of a turbine= input into compressor
How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
What is the technical reason for deterioration in performance of a gas turbine when the ambient temperature rises?
As the surrounding/ambient temperature increases, the temp of air entering the air compressor increases which means that the it's specific volume of air increases. Since the work of compressor = delta pressure x specific volume of air, then as the specific volume of air increases the work input of compressor increases and this is a problem because the total out put power of the turbine = work of the turbine - work of the compressor, so as the work of compressor increases, the total out put work of the gas turbine decreases. And that's why the efficiency of gas turbine is better in winter than in summer.
Why the temperature and the pressure of gas are decreasing after flowing out from turbine?
The gas (working fluid) having flown through the turbine does some work on the turbine, converting its thermal energy into mechanical work produced by the turbine and coming out as an expanding gas with lower temperature and pressure.

How a gas turbine work?
Basically, a gas turbine is powered by gas under pressure, The gas is pressurized by burning some type of fuel such as kerosene, jet fuel, or propane. That heat causes air expansion, and the subsequent inflow of air makes the turbine spin. A gas turbine consists of three main parts; a combustion chamber, a turbine and a compressor. Air and fuel are mixed in the combustion chamber where it is ignited and increases in speed and power. This power is directed over the turbine blades which spin the turbine and power the compressor. It's a pretty simple process: heated fuel causes pressure and air expansion. The expanded air causes a turbine to spin. That is how gas turbines like jet engines work.
How do I replace a gas turbine in a Ford Focus?
There are many online sources showing step by step directions to replace a gas turbine. You can also use the manual or take the car to a mechanic.
Why is the gas turbine called as the power plant?
A gas turbine is one type of power plant. It produces power by burning gas to turn the turbine.
What is the effect or reheater in the gas turbine?
1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
When was Gas Turbine Research Establishment created?
Gas Turbine Research Establishment was created in 1959.
Why the gas turbine needs 3 bucket stages only in 110MW TURBINE?
because all gas turbine has three stage buckets
What is the function of IGV in gas turbine?
The function of IGV in a gas turbine is to prevent surges and stall conditions.
