Jet Ratio: it is defined as the ratio of the pitch diameter (D) of the pelton turbine to the diameter of the jet (d). It is denoted by m and is given as
m = D/d (=12 for most cases)

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.
Why is there a little spiral on the front of jet engines?
So that it is easier to tell from afar whether the turbine is rotating or not, for safety reasons
What is difference between pelton wheel and turgo turbine?
pelton turbine is used for high head low flow but the turgo turbine is used for low head high flow, in pelton turbine number of jet can increased but in turgo it can't be done, in pelton the water hits the bucket once at a time but in tugo it hits more than one
What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
Designing an axial fan for aircraft?
what do you mean? axial compressor (or) axial turbine? Their missions are different. Design for axial compressor or turbine, must be consider their performance. The performance is characterized by - pressure ratio, rotational speed and efficiency. The details of how to design axial fan, are very complex.
What is in jet fuel?
Jet fuel is kerosene base turbine aviation fuel
What is the differences between gas turbine and turbine engine?
That depends on what you are thinking of. Gas turbine usually refers to all types of jet engines and engines that use the 'jet engine' concept. The turbine engine you are thinking of could be one of a few things, like a jet engine for military aircraft, turboprop, or turbofan for commercial engines.
What kind of engine is a jet engine?
Gas Turbine.
How does the suckers on starfish work?
Jet turbine technology
Why did they change the name of the gas turbine to the jet engine?
They use both terms. A turbine engine that's being used in an aircraft is a "jet engine," and a turbine engine that's being used in a ground-based application is a "gas turbine." Sometimes it's the same engine--the Lycoming engine used in the CH-47 as a "jet engine" is also used in the M-1 tank as a "gas turbine."
When two or more turbine wheels are used in a jet engine what is placed in front each turbine wheel?
turbine stator (nozzle diaphragm)
Did LEster Alan Pelton invent the water turbine?
Pelton invented a free jet water turbine called the Pelton wheel or Pelton turbine
What is the hot section of a jet engine the compressor or the turbine?
the hottest point of the jet engine is the combustion chamber
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 jet engine engine pressure ratio?
The pressure ratio in jet engines is the ratio of pressure between the entrance of the compressor and the exit of the compressor.
What is governing of impulse turbine?
Basically governing of a turbine is controlling the speed of the turbine as the load keeps varying. The turbine needs to rotate at a constant speed. The governing of an impulse turbine is done by varying the jet of water that hits the buckets of the runner. This is done by using a spear arrangement in the pen stock. A pen stock is a type of pipe that provides the jet of water.
How do jet engines accelerate mid air?
By increasing the firing in the Turbine.
