What is the purpose of crossfire tubes in gas turbine?
Crossfire tubes in gas turbines serve to enhance the combustion process by ensuring that the flame is stabilized and maintained across the combustor. They provide a pathway for the combustion gases to flow from one combustion chamber to another, promoting uniform temperature distribution and efficient fuel combustion. This design helps prevent flameout and improves overall turbine performance and efficiency.
What is dryness fraction with answer?
If the water content of the steam is 5% by mass, then the steam is said to be 95% dry and has a dryness fraction of 0.95.
Dryness fraction can be expressed as:
ζ = ws / (ww + ws) (1)
where
ζ = dryness fraction
ww = mass of water (kg, lb)
ws = mass of steam (kg, lb)

What is 'x' in steel grade 'x-70'?
That means that 'x' is made from steel of the said kind (steel grade).
When was tensile strength discovered?
Tensile strength was discovered by Leonardo Da Vinci in the 1800s.
Why clapper box provided on a shaper?
A clapper box on a shaper is designed to hold the cutting tool while allowing it to lift off the workpiece during the return stroke. This prevents the tool from dragging across the surface, which could damage both the tool and the workpiece. By lifting the tool, the clapper box ensures a clean and efficient cutting action, enhancing the quality of the machined surface.
What is an optical transducer?
A optical current sensor is used to measure current, In CT there is a use of iron core but as the rating of current to be measured increseS the CT saturation occurs this will leads to inaccurate representation of The current, but this does not ocur in OCS ,It uses light to measure the current,Current flowing in a conductor induces a magnetic field, which, through the Faraday effect, rotates the plane of polarization of thelight traveling in a sensing path encircling the conductor.thus by measurin this rotation the current is measured.(by GAURAV GAUR LNT, INDIA)

Can you hydro through a gland steam condenser?
Yes, you can hydro through a gland steam condenser, but it requires careful consideration of the system's design and operating conditions. Hydro-testing should be conducted at appropriate pressures and temperatures to ensure the integrity of the condenser without causing damage. It's essential to follow manufacturer guidelines and industry standards to avoid compromising the equipment's performance. Proper drainage and venting during the process are also crucial to prevent water accumulation and potential damage.
The shaft ends of the faster moving wheels and gears have conical points that ride in small jewels (ruby usually). This assures minimum friction for the movement. The "odd" number jewel is at the back of the second hand.

What is difference between Stud and stud bolt?
stud has all its length threaded and it is used with two nuts, but the bolt has one end closed and the other end is threaded ,it is used with a single nut.
What is the Coefficient expansion steel?
The coefficient of expansion for steel refers to its linear thermal expansion coefficient, which quantifies how much the material expands or contracts when subjected to temperature changes. For steel, this coefficient is typically around 11 to 13 x 10^-6 per degree Celsius. This property is crucial in engineering and construction, as it influences the design and integrity of structures and components subjected to temperature fluctuations. Proper consideration of thermal expansion helps prevent structural failures or distortions.
What is the formula for calculating the pitch of an inch screw thread?
pitch = 1/Threads per Inch
So for a 1/2 - 20 thread the pitch is .1
How much 90 psi air is available in 1 tank with peak pressure of 135 psi?
This depends on several factors. A smaller tank will have less air available at the same pressure than a larger tank. Also, the cubic feet per minute rating of the compressor is a factor, with a larger compressor rating allowing for more usage.
What is the function of stern tube system?
The stern tube in marine engineering allows the propellor shaft to penetrate the hull of a ship and prevent the ingress of water. It also acts as a bearing and lubricates that part of the shaft.
