Its not necessarily heavier (thicker is the wrong term),
but it is more carefully aligned - and the curves are gentler.
Why is alcohol used in manometer?
Manometer is a device that is being used to measure pressure. It uses alcohol because it has a low vapor pressure.
What are the effect of climate change in engineering?
Climate change has a great effect in many areas and one of this is the engineering field. It can slow the process of building an infrastructure, damage the flood ways and buildings, and can cause a great destruction to the community.
What material type used for cryogenics?
Metals not plastics. What is your goal?
For the most part metals with some mixture of carbon see the best results from a cryogenic treatment.
However, materials such as aluminum, copper, and other metals have had excellent results as well.
How do you calculate the size of an air conditioner for a switch gear room?
Same as any other room with one possible exception, determine the present heat load in the room but also allow for any future heat generating equipment you may install there and that is what you buy. Bearing in mind you do not want to grossly oversize the initial install allowing for equipment that is 10 years away. Better to make provisions such as installing the curb and ductwork for a second unit now but actually wait on installing and commisioning the unit until the new equipment arrives. Otherwise just buy what you need for now either way the calculation is the same equipment = heat load. The literature on the switchgear should provide the heat load information.
What is pump down in water chillers?
first fit a low pressure gauge to the compressor suction line and start closing the liquid receiver discharge line. through
this way all the refrigerant comes to the liquid receiver after completing the cycle but not allowed to go back to the system. during this process system become low pressurised and become trip. this
is how we pump down the system

How many rotor blades does a Chinook helicopter have?
Six - The Boeing CH-47 Chinook is a versatile, twin-engine, tandem rotor heavy-lift helicopter. Its top speed of 170 knots (196 mph, 315 km/h) was faster than utility and attack helicopters of the 1960s and even many of today. Its primary roles include troop movement, artillery emplacement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external-cargo hooks.

Why petrol engines are faster than diesel engines?
Petrol engines are widely considered to be the most efficient of engines, because they are more refined than diesel. Since diesel is not completely refined, it cannot completely combust and so does not (in theory) produce as much energy per litre of fuel as a petrol engine. However, some diesel engines can be made to be much more efficient than petrol engines because they have a different type of fuel, and burn it in a different way.

Formula module in helical gear?
the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth
Is there any copper inside an arc welder?
Like any mechanical tool, machine or similar engineering equipment, an arc welder will have lots of different materials inside it.
An arc welder is an electrical machine and any electrical machine must have wiring inside it. Most electrical wiring will be made of Copper. So yes, there is likely to be some Copper inside an arc welder.
