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.

Function of evaporator condenser expansion valve and condenser?
Condesor- cools the liquid formed gas after compressor compresses. After condensor it pass through the expansion valve, then again liquid formed gas expanses to gas form and produses cooling .this cooled gas then passes through the evaporator coils
a molded projection located where the ceiling and wall meet; in classical architecture,the projecting top of an enablature;
Crown mouldings are used to ease the transition from ceiling to wall, while adding character and elegance to the room. Crown moldings are available in an extensive array of sizes and styles,
As with most other interior design decisions, the choice of size depends largely on style and preference. The size of the space must be considered, along with the depth of the moulding relief, a smaller moulding may suffice for a higher ceiling if it has heavier, bold relief.
There ae many good sources but You can find a good selection at www.buymoldings.com
There are many, many examples. Generally, rotating shafts are used to transmit power from a producer to a user device. A few examples: Drive shaft in an automobile- transmits power from the engine to the wheels. Propeller shaft in a ship- transmits power form the engine to the propeller. Pump shaft- transmits power from a motor to the pump impeller. Rotating shafts are all over the place. You can find dozens of examples in the typical appliances in any typical home.
What is the difference between SMACNA and DW144?
Both methods are using in HVAC Ducting work mostly about 99% that smacna is using in that same.
the answer is b cylinder just took the test its not the combustion chamber
It's seems as though you have answered the question yourself. You have stated exactly what it is (manufacture and model number). It was made in China and their exclusive distributor here in the US is "Instrument Sales & Service" out of Wilmington, DE. In case you need it, their number is 1-800-874-7637.
You will need a footing to support a moment of 21,000 ft.lbs.
Moment = Arm x Force
Moment = 1000 lbs. x 14 ft. = 21,000 ft.lbs.
Thermal insulators feel warm to the touch, as they do not conduct much heat away from your hand. The insulator itself will be at ambiant temperature once equilibrium has been reached and so is the same temperature as its surroundings.
How much are suspension cables in suspension bridges allowed to stretch?
Strictly speaking, I do not know the answer
Can you reduce the heat treatment time in carbon steel through normalizing instead of annealing?
can we reduce the heat treatment time in carbon steel through normalizing instead of annealing?
Why shouldn't you breath in the fumes from a soldering iron?
It's not healthy!! Though they are safer than they used to be, fumes released from molten solder and flux could contain chemicals that might be a long-term health hazzard. It is prudent to keep exposure to a minimum.
mw (mega watt) is one million watt and that is a unit of electricity, whereas
kwh(kilowatt hour) is rate of consumption of one thousand watt of electricity for one hour.
AnswerFirst of all, let's get our symbols correct. There are nounits having the symbols: 'mw' or 'kwh'!Presumably, you are either trying to express a 'milliwatt' (mW) or a 'megawatt' (MW), and a kilowatt hour (kW.h)?
You cannot convert either milliwatts or megawatts into kilowatt hours, as they measure completely different quantities!
The milliwatt and the megawatt both measure power(not 'electricity'!). The kilowatt measures energy(which is not a 'rate of consumption'!).
What is the difference between a BLOWER and COMPRESSOR?
There is no difference. A blower is just a term used for a supercharger.
A compressor is any machine that compresses a gas for many different purposes. A supercharger in its many forms is a type of compressor
What are the advantages and disadvantages of axial compressor?
Axial-flow compressors have the following advantages:
-High peak efficiency.
-Small frontal area forgiven airflow.
-Straight-through flow, allowing high ram efficiency.
-Increased pressure rise due to increased number of stages with negligible losses.
They have the following disadvantages:
- Good efficiency over narrow rotational speed range.
-Difficulty of manufacture and high cost.
-Relatively high weight.
-High starting power requirements (this has been partially overcome by split compressors).
How many mini-buses are needed to carry 237 people when the mini-buses carry 11 people each?
approximately 23476 busses are required because America is full of fatasses
800cc of what? It all depends on the substance in which is is 800cc.
CNC stands for Computer Numerical Control. It refers to a type of milling or manufacturing machine that is computer guided, with the ability to change tools, bits, blades, or tips.
What is the difference between us invert level and ds invert level?
US = Up Stream invert level
DS= Down Stream invert level
If detailed on a manhole, the difference being the gradient of pipe in chamber from one end to the other.
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
A hydrophore system is a system comprising a powerful pump unit and a pipeline that is designed to increase the pressure of water from the urban mains so that water can be supplied to the higher storeys of a tall building.
