Answer:
The efficiency of a DC generator is maximum when those losses proportional to the square of the load current are equal to the constant losses of the DC generator. This relation applies equally well to all rotating machines, regardless of the type of machine.
Explanation:
Answer:
the pressure reading when connected a pressure gauge is 543.44 kPa
Explanation:
Given data
tank volume (V) = 400 L i.e 0.4 m³
temperature (T) = 25°C i.e. 25°C + 273 = 298 K
air mass (m) = 3 kg
atmospheric pressure = 98 kPa
To find out
pressure reading
Solution
we have find out pressure reading by gauge pressure
i.e. gauge pressure = absolute pressure - atmospheric pressure
first we find absolute pressure (p) by the ideal gas condition
i.e pV = mRT
p = mRT / V
p = ( 3 × 0.287 × 298 ) / 0.4
p = 641.44 kPa
so
gauge pressure = absolute pressure - atmospheric pressure
gauge pressure = 641.44 - 98
gauge pressure = 543.44 kPa
Lol please give me points
The three previous manufacturing revolutions that Mr. Scalabre mentioned and their year of occurrence are:
- The steam engine in the mid-19th Century
- The mass-production model in the early 20th Century
- The first automation wave in the 1970s
<h3>What is a Manufacturing Revolution?</h3>
This refers to the process of change from a handicraft economy to industry production-based production.
Hence, we can see that Mr. Scalabre believes we are not growing in productivity because there has not been enough automation to perform the tasks needed.
The effect of robotics is making an impact on productivity because a lot of complex, difficult tasks are done by machines.
3D printing has made an impact on productivity because there is a reduction in the pressing cycle and errors due to negligence are reduced.
The role the engineers have to play in the next revolution is that they would have to produce mathematical model that can be used to produce better AIs
