What is failure mode and effects analysis?
The FMEA is a risk assessment tool that helps systematically define where potential points of failure are located, help define the critical nature of the problems and logically layout the plans to resolve them.
How do you convert volume per hour to volume per day?
Some volume/hour (24 hours/1 day)
= some volume/day

How is 63.2 percent derived from using one time constant?
These values are derived from the mathematical constant e, specifically 1 − e − 1 and e − 1 respectively.
when you do engineering at offshore, it is known as offshore engineering. It is just the opposite of on shore engineering .

How can you transmit voice signal using ask modulation?
The only way is to digitize the audio signal and send it as data
They are short stubby wings protruding from the underwater body of the ship to keep it from tilting side-to-side in rough seas.
A36 and Q345 are not directly equivalent, as they are specifications from different standards. A36 is an American standard for structural steel, while Q345 is a Chinese standard for low alloy structural steel. Q345 generally has higher yield strength and better toughness compared to A36. When considering material selection for a project, it is essential to compare their mechanical properties and ensure they meet the required performance criteria.
How do you find the voltage at a point in a circuit with respect to a negative voltage?
First of all, 'voltage' means potential difference -and you cannot have a potential difference 'at a point'. Similarly, you cannot have a 'negative' potential difference, so it doesn't make sense to talk about a 'negative voltage'.
Your question, therefore, should read: 'How do you find the potential at a point in a circuit with respect to a negative potential?'
The answer is that you simply connect a voltmeter between the two points. The reading will give you the value of the potential. If it reads upscale, then it'll be positive; if it reads downscale, then it will be negative (i.e. even more negative tan the reference potential).
Biggest invention of 21st century?
Perhaps the car, telephone, computer, television, or the iPhone.
the car, telephone, computer and the tv arent 21st century or important it would have to be a form of medicine
What is maintenance in engineering?
It is one thing to engineer or build a machine, it is totally different thing to keep the machine running a its best. Maintenance is the work that keeps things running and finds future problems before the problem stop the machine running at all. Maintenance is also fixing problems that stop the machine so the machine can be restarted
How do you calculate the take off for a but-weld 45?
Nominal pipe size times 5/8. (NPx5/8)
Ex if np off 45 is 6" then 6 x 5/8 = 3.75 or
3-3/4"
5 HP is equal to 3.7 KW. 415 Volts 3 phase 50 hz system takes 6.29 amps. Same 3.7 KW motor with 230 volts, single phase 50 hz takes 18.9 amps. Same 3.7 kw motor with 230 volts three phase 50 Hz takes 11.1 amps. These are full load current with 0.85 assumed power factor.
To arrive at over load, you may 5 to10% over load and set the over load setting.
What is the Meaning of tractive force?
Tractive force is 'static friction'. Like the friction experienced between your car tyres and the road when accelerating from a stand-still.
Who used a cathode ray tube to study matter?
you may wonna check this but i believe it was j.j Thomson
In a bevel gear is the torque increased decreased or constant?
There are 3 possibilities:-
1) If the pinion has less teeth than the wheel - torque is increased.
2) If the pinion has more teeth than the wheel - torque is decreased.
3) If the pinion has the same number of teeth as the wheel - torque is constant.
Why is refrigeration all about heat?
Because we can't make cold, we can only remove heat. So refridgeration is always about moving heat away from one spot and dumping it somewhere else.
What major criteria must product or process meet in order to be considered emerging technology?
The major criteria must a product or process meet in order to be considered emerging technology is its pureness and usefulness.
What is a lossless transmission line?
A lossless transmission line is when no energy is lost during transmission of energy from a particular source to destination by a certain material, ie. copper wire. In other words, this material that transmits energy, absorbs none of the energy transmitted. No energy is lost to the material during transfer of energy. It is like saying it is an absolutely perfect conductor having no resistance.
