@@prabusenthil4746 Not necessary. There are three parameters, temperature, pressure, and volumn, so the change can be in either combination. For example in idea gas law Pv=RT, there are three parameters.
The ton you looked up is a different ton used for cooling towers or chillers. The conversion of 1 ton to 0.75 kW in the context of chillers is not a fixed rule or universal constant. The value of 0.75 is a good estimation between cooling tons and kilowatts, although this number can vary between different chillers.
Thank you for youyr video. I believe that the conversion factor for the "100-ton-chiller" should be: 3.517 kW/ton refrigeration. Source: www.unitconverters.net/power/ton-refrigeration-to-kilowatt.htm
So, I have a few homes. One for me, one for my father and one for my inlaws. My son is about to move out as well. I considered building one spreadsheet with addresses on the X and various readings on Y. On Y, I could have 'water', 'power', 'heat' and so on. Now every heading will have several columns. e.g. January reading| Feb Reading| March | April| and so on.after each column, I want to see how many units we have used. And in the next column, there should be the difference already calculated. Can you please throw some ideas...
Thank you so much for your video. I recently became interested in energy, and this helps me understand better because I come from a non-traditional background.
Forecasting typically requires the annual increase or decrease rate. At the moment, I don't have a widely accepted rate that I can use as an example for energy forecasting. However, I have created a video in the past on forecasting retirement investments, and the concepts involved are similar. Once you have your data, you can simply plug it in. I recommend watching the video below to see if it provides any assistance. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-daYF4ksCBW4.html
"Fraction load" refers to the estimated percentage load of a particular equipment. For example, if the maximum output power is 50 hp, but the equipment is only running at 50% load, then it may only generate 25 hp. Fraction load information can be obtained from the plant supervisor and is not based on any derivation.
I mean…as long as we are doing this transaction on planet earth, it shouldn’t matter mass vs force, so…lbf vs lbm vs slug vs kg vs N…idk it tends to get odd reactions to point out such things to muggles
For step 2, why are we using cv in our calculations? I imagine this would cause significant error since both pairs of states (2 and 3, as well as 1 and 4) are far from the nominal value of 300 K suggested when we use the 0.718 as our specific heat in constant volume.
You are correct. Technically, we are supposed to use Cv with their corresponding temperature for getting more accurate result. In this example, our main focus is to show how Otto cycle works so we simplified the calculation by treating Cv as a constant.
@@DrGucci Since my previous comment, I've seen such in practice. Please forgive my hastiness, and thank you for your timely response! I look forward to learning more from your videos in the coming semesters.
Are you talking about how to calculate quality, i.e. the percentage and the volume of liquid and vapor? Try the video below. If that is still not what you are looking for, you can type in your problem with the description and I will see what you are looking for. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PqhjP2m6msc.html
No. It is just what Thermo EOS states: if knowing two individual independent properties (for example, temperature and pressure), all other properties can be determined. 😆
I saw your videos. I got a video there you talked about tensile test. That was very Useful video. Could you please tell me how to find out Guaranteed tensile strength and guaranteed tensile strain from tensile test data.
You can double check your work first. I have had hundreds of students in class completed their graph with this video. They all got the correct graph so the tutorial should be correct. If you still have questions, you can leave message here.🙂
@@keimchi8035 You can double check all your data and see you have the same number with mine. Especially make sure your column E and F have the same number with mine. Also double check if you chose column E & F when plotting the trend. Good luck!🍀
Excellent explanation on the 0.2 offset yield point. I am a current Aircraft Engineering student. I have been trying to get a better explanation about this concept. You save me a lot of time. Thanks a million.
