The exhaust temperature of gas turbines is very high due to the large amount of energy input into the inlet air by the combustion of fuel in the combustion chamber.
The exhaust gases are often up to 500 Degrees C (940 Degrees F) but this can vary wildy depending mainly on load.
The air cycle machine (ACM) is driven by turbine engine bleed air that first passes through a primary heat exhanger (much like an intercooler for a turbocharged automotive engine) that significantly lowers the temperature of the 300-500 degree bleed air. After leaving the primary heat exchanger the air flows into a compression turbine that increases the pressure of the air and also increases the temperature. After leaving the compression turbine, the air flows into a secondary heat exchanger that once again lowers the temperature of the air. At this point, the air is at extremely high pressure and relatively low temperature. From the secondary heat exchanger the air flows into the "expansion turbine" where this high pressure air is used to drive a turbine wheel that performs several functions: 1. It extracts energy from the high pressure air, 2. Allows the pressurized air to expand, 3. Drives the compression turbine. The extraction of energy from the air and subsequent expansion of the gases drastically lower the temperatures of the air. In fact, the air temperature is lowered so much that often times hot bleed air is bypassed around the ACM and ducted to the air coming out of the expansion turbine to raise the temperature above freezing. The output air that is coming out of the ACM is then sent through a moisture removal system that essentially uses a fine mesh weave to collect small droplets of water. This removal of moisture helps to control the humidity of the air entering the cabin and it also prevents icing downstream in the system.
i think the temp inside the cyl during combustion is 500c' to 600c'.
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
Most stainless steels have a strenght of at least 500 MPa. Most alloy steels also have that strength.
The exhaust gases are often up to 500 Degrees C (940 Degrees F) but this can vary wildy depending mainly on load.
The temperature range of a car exhaust ranges from 500 to 700 degrees Fahrenheit. An airplane exhaust can reach temperatures of 1200 to 1400 degrees.
A general guide is that the turbine should be a minimum of 30 feet above any trees or buildings within 300 to 500 feet.
They are 500-1000 degrees F, depending on the engine.
some are more than 500 feet

Car exhaust can reach temps of 500 degrees F. With the hottest points being the exhaust manifolods/headers, and the catalytic converter.

approximately 500 gallons each that must be regularly changed.
The boiling point of water at 2 500 m is 91,673 0C.
1 wind turbine can generate 500 houses per year (kw)
It takes about over 500 people to build a turbine wowza!
