17 cases, energy efficiency issues
Thread Content
It is said that energy consumption decreases by 97.3% after the efficiency improves; I’d like to know by how much it increases. Which option do you people choose? I couldn’t calculate it with complete accuracy, so I chose 2% and option A. I’m not sure if that’s correct
What is the title? I kind of forgot
What this question is asking is: the heat loss seems to be 77,550, and by improving the thermal efficiency, it’s necessary to calculate by what percentage the improvement has been. My calculation also gave a result that was slightly off from the correct answer, so I chose A.
I can’t remember the specific details; it’s water, electricity, steam, and compressed air. . . , then it states that the efficiency increases to 97.3; calculate the increase in efficiency and determine the energy consumption loss after the improvement
Speaking of this topic, I remember a thermodynamics problem from this morning that asked us to calculate the thermodynamic efficiency. How does one go about calculating that? The answer I got is quite off…
That question seems to involve calculating effective work divided by the decrease in effective energy; there’s an answer to it
I remember there was also a reactor connected in parallel, used for calculating the volume of the reactor; I calculated it to be 6
Did you calculate 92%? Choose A
I’d say it’s also 6; the total volume on the top is twice that of the bottom. The total on the top is 18, while it’s 9 on the bottom. The first value is 3, and the result is 6
I calculated the answer to this question as 2.02, so I choose A
