Answer:
Control mechanisms
Explanation:
Organizational chart of any company will give details of different aspects of the company such as the major sub-units of the organization with the names of team leaders for different sub-units, it can also give you the span of control and the division of work within the company. However, the chart can't show you control mechanisms of different departments.
B
Now this is a guess sorry but i am positive on this guess
Answer:
Midnight on the birthday. Hope this helps!
Answer:
Check below for answers and explanations
Explanation:
Automation is a technology by which processes that are normally meant to be controlled by humans are electronically controlled. These can be through the use of robots, computer aided machines, etc.
For small scale industries, expensive automation should not be employed, it should rather be low cost, because of the financial abilities of these firms.
Low cost automation will improve the production of small scale industries in limited time. Humans cannot match up with machines that have been incorporated with programmable comptrollers in carrying out production processes. Such machines operate at a higher speed and Efficiency.
For example, In a small packaging company, microrobots can be made to serve this purpose while saving the continual cost of labour and at the same time ensuring efficiency.
A small mechanic workshop that decides to employ an automatic diagnostic tool will be more efficient and productive than the one that uses manual approach.
Answer:
a) Mechanical efficiency ()=63.15% b) Temperature rise= 0.028ºC
Explanation:
For the item a) you have to define the mechanical power introduced (Wmec) to the system and the power transferred to the water (Pw).
The power input (electric motor) is equal to the motor power multiplied by the efficiency. Thus, .
Then, the power transferred (Pw) to the fluid is equal to the flow rate (Q) multiplied by the pressure jump . So .
The efficiency is defined as the ratio between the output energy and the input energy. Then, the mechanical efficiency is
For the b) item you have to consider that the inefficiency goes to the fluid as heat. So it is necessary to use the equation of the heat capacity but in a "flux" way. Calling <em>H</em> to the heat transfered to the fluid, the specif heat of the water and the density of the water:

Finally, the temperature rise is:
