Jet exhaust is composed of various gases, with water vapor (steam) being a significant component. Typically, steam constitutes about 5% to 10% of the total mass of jet exhaust, depending on factors such as engine type and operating conditions. The actual percentage can vary, but moisture from combustion contributes notably to the overall exhaust composition.
What else can I help you with?
What engines did the titanic use?
Two triple expansion steam engines and an exhaust turbine
What is the working principle of steam jet ejector?
it is not based on bunoullies theorem it is based on mach number.when sonic speed of steam converted to supersonic steam by nozzle vacuum is created.
How do you get vacuum in industry?
Vacuum is generated by using Ejectors. 1. steam jet ejectors 2. water jet ejectors. may be single, double or 3 effect.
What are the advantages and disadvantages of a condensing and non condensing steam engine?
Condensing steam engines are more efficient as they utilize the latent heat of steam condensation, allowing for greater energy extraction from the steam and lower exhaust temperatures. This leads to reduced fuel consumption and increased overall efficiency. However, they require more complex systems, including condensers and pumps, which can increase maintenance and initial costs. Non-condensing steam engines are simpler and cheaper to build and maintain but operate at lower efficiencies due to higher exhaust temperatures and energy loss.
Why does the largest heat loss occur in a condenser in regard to steam?
heat losses in condenser in percentage
How does the after bunner jet engine work?
Jet fuel is sprayed into the exhaust gas steam and ignited, as this happens, the end of the primary nozzle constricts hydraulically and the result is increased thrust as the jet exhaust is "after burned".
Can you pumped exhaust steam directly to boiler?
No. Exhaust steam must be condensed back into water before being pumped back to the boiler. High pressure exhaust is often used to heat production or heating equipment, returned to a condensate tank then pumped to the D/A before being returned to the boiler. Low pressure (vaccuum) exhaust is condensed by a jet condenser or shell and tube condenser before being returned to the D/A.
What does jet steam mean?
Jet steam is the pressure steam that is released by the nozzle of the jet engine. Using fuel and air to burn produces this steam that is hot and under pressure for the use of the turbine and provide the thrust needed.The above equations shows this. Normally the jet steam to be discharged is under high temperature and high pressure and it is used to give adequate thrust to the aircraft or to other vehicles having jet engines. Besides imparting thrust, the jet steam plays an essential role of cooling and thermal control of the jet engine.
Why you are maintain the vacuum in steam turbine explain me briefly?
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
What was discovered by James watt?
That the efficiency of a Steam Engine could be improved by condensing the exhaust steam.
Can a turbo cause excessive steam to pass out of the exhaust?
For steam to come out the exhaust you probably have a bad head gasket or a cracked head. If the turbo had an oil seal fail it would cause blue smoke to come out the exhaust.
What is air which comes out from the nozzle of jet engine called?
exhaust
Why turbine blades are largenr in size at exhaust end?
Because the steam expands as it passes through the turbine. The steam velocity through the turbine is constant from steam chest to exhaust hood (though it changes in each stage). Thus, the space needed for the steam to expand needs to be expanded to correspond with that expansion of the steam.
Where is the jet steam located on earth?
between troposphere and ozone
Why was the Corliss steam engine remarkable?
The Corliss steam engine is remarkable because of the design of the valves which control the intake and exhaust to the steam to the cylinder.
Does a Jet have a motor?
Yes, a jet has engines, which are often referred to as jet engines. These engines operate on the principle of jet propulsion, where fuel is burned to create high-speed exhaust gases that propel the aircraft forward. Unlike traditional motors that might use propellers, jet engines typically provide thrust directly through jetting out exhaust gases.
What is the working principle of steam jet air ejector?
The steam jet air ejector works on the principle of converting steam pressure energy into velocity to create a vacuum. High-pressure steam passes through a nozzle, entraining air or gases, and carries them out with momentum. Key points: Steam expands through the nozzle, lowering pressure. Air/gases are entrained into the stream. Mixture is compressed and discharged. Often used in condensers and vacuum systems. Interestingly, concepts of flow and entrainment in such systems can be compared to textile processes, like how Damask Air-Jet Woven Labels utilize controlled air jets for precision weaving. Just as ejectors guide gases efficiently, Damask Air-Jet Woven Labels rely on airflow to align threads seamlessly.
