Mechanical Engineering
Mechanical Engineering is a branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. Mechanical engineering involves application of the principles of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, materials science, electronics, and mathematics.

A dome valve might be described this way. Take a solid ring to use as a seat. Now cover the ring with a disk shaped like a contact lens or like a snow saucer. That curved surface will sit inside the ring to seal the valve, and to open it, a lever rotates the disk out of the way of the opening. Use the link to a picture of one. Clyde (in the UK) makes them, as do others, but this picture is animated! You'll get to see the dome valve in action, and that will probably make any further explanation unnecessary.
Why you learn carnot cycle while it is not use in reality?
because it is the best theoretical engine. our aim is always to make our practical engine as close as that of carnot. if u don't know about the carnot cycle then how will u do that.
When is cryogenic process considered adiabatic?
A process can be considered to be adiabatic if heat loss/transfer is zero, or negligible compared to the system.
If the system contains for example, 1 x 10^6 J of heat energy and 3J are lost in a process, the process can be considered adiabatic.
What is the opposite of elastic?
The opposite of elastic is inelastic, where a material cannot stretch and rebound. A material without this quality could be "inflexible" (rigid, stiff) or one that did not rebound, termed "plastic" (deformable).
Elastic suggests that the material recovers its original shape after an applied load is removed. Plastic means that it doesn't recover its shape. Steel is an example of an elasticmaterial, when it is loaded within its capacity. It becomes plastic if it is overloaded. Concrete can be considered an elastic material only in compression.
Are there readily available substitutes for gold in industrial applications?
6 week old turds have the same properties as gold. Try it out.
How do you install a hockey puck lock on a express van?
---- Hey, I hate to tell ya' but drilling is the easiest way and the only way unless you want to weld it on. my e-150 has locks on the side and rear with a weather-guard bulkhead behiend the seats. trust me there worth it.
How do we can calculate weld deposition rate for submerged arc welding?
Check wire feed rate of saw wire (metre/min.)with this we can check deposition per minute.
by multipling this with 60 , we can get deposition per hr.
How cooling tower height is significant for cooling tower design?
There's quite multitude of things that impact a cooling performance. Specifically the height of the tower impacts on the the drafting air through the tower. See "Air Cooled Heat Exchangers and Cooling Towers" by Kroger for something more indepth.
What is mean by Blowing factor in steam blowing?
Disturbance Or Correction or K Factor in steam blowing in Power Plants is the ratio of Drag created during steam blowing to the drag occurring during Maximum Continuous Rating.
Equation of disturbance factor K is shown as below: K=ΔP1/ΔP2
ΔP1=PD1－PS1；ΔP2=PD2－PS2
ΔP1:Difference pressure of steam drum and corresponding super heater during steam blowing-out.
ΔP2: Difference pressure of steam drum and corresponding super heater in normal operation of boiler
What is the Wall thickness for schedule 80 4 black iron pipe?
The wall thickness of 4" Sch 40 pipe is 0.237 inches.
The outer diameter is 4.5 inches and the inner diameter is 4.026 inches.
What is spring loaded inverted pendulum?
The Spring Loaded Inverted Pendulum (SLIP) model is an attempt at describing running motion through a spring-mass model. The SLIP model is depicted as an energy conserving system with a point mass as the body and a massless spring as the leg and foot.
The deformation rates as high as A 2m s b 25m s c 250m s d 500m s are used in high velocity forming of metals.

What are the elementary parts of a vibrating system?
spring
mass
dashpot (viscous damper)
with these you can model any vibrational system via
mx''+cx'+kx=f(x) where f(x) is the exciting force
To stop electrolytic action causing corrosion. Dissimilar metals (especially steel and aluminium) form a battery when wetted with water. This battery will cause a small current flow in the metals which will then eat away at the aluminium. Coating one or the other components, provides an insulator, which stops the battery forming.
The ports of the angle valve ( Inlet and outlet) are oriented at an angle 90 deg.
