What is needed to produce energy?
many things. one, energy source. For humans, that's food and oxygen. Oxygen is used in aerobic respiration, which produces about 32 ATP (which is energy that our body can use). Food contains nutrients and sugars that help produce energy. ATP can be used to restart the cycle, and break down food to yield more ATP/energy. As for something like plants, they use photosynthesis. This uses the Sun's light as energy to "kick-start" the energy process. they use Anerobic (as suppose to human's aerobic) respiration. this yield about 8 ATP (which as you can see, is less than the 32 ATP aerobic respiration yeilds). They then use that ATP to carry out all of it's functions, since ATP is energy.
So to sum it all up,Oxygen (only in aerobic respiration), ATP, light (sun's light), and Carbon are needed to produce energy.
What are the Importance of instrumentation in power plant?
in my own idea, the importance of instrumentation in system or process is play a very significant role. as based on the definition, it control the process variables in any production or manufacturing area. without instrumentation there will be no more machines, devices, and any electronics or mechanical machineries or any devices in this world that is relevant to measurement and control. importance of instrumentation is that it is the one who manipulated and manufactured everything especially in an industry that prone of more automated machine. instrumentation also provide monitoring of an industry how the work is going on and make the work for people to be easier,reliable, consistent, less in energy and save in time.
