An 800 MW electric power plant

AI Thread Summary
An 800 MW electric power plant operates at 30% efficiency, meaning that 30% of the energy input is converted to electricity, while the remaining 70% is lost as waste heat. To calculate the waste heat discharged per second, one must convert the electrical output into heat units, considering the efficiency. The discussion includes a light-hearted exchange about the meaning of efficiency and references to a nebula. The key focus remains on understanding the conversion of power units to determine waste heat. Ultimately, the calculation of waste heat is essential for assessing the plant's environmental impact.

An 800 MW electric power plant has an efficiency of 30%. It loses its waste heat in large cooling towers. Approximately how much waste heat is discharged per second?"

Always nice to see this.



But if it's 30% efficient, what does that mean?

Hi Thankful_LV ! Welcome to PF! :smile:

Hint: MW are electric units.

How do you convert them into heat units? :smile:

Indeed it is! That's exactly what I had in mind.

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
