Yes

It is (l-l_0)/l_0. That is also what I did in the video, which I used elongation devideed by the original length.

Glad it helps!

Isobaric means constant pressure and is not related to volume. So the volume can increase decrease or remain the same.

@@DrGucci usually during isobaric expansion the volume will increase and isobaric compression means volume will decrease right?

@@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.

@@DrGucci yeah ok sir , got it thank you.

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.

The numbers are sllightly different bewteen books. I would consider 0.037452 and 0.037408 smilar and both correct.

They are both correct. PV=nRT is commonly used in Chemistry. I am in Mechanical and Pv=RT works better for me.

That is UA-cam, not me

320 kPa is a known from the problem description. The problem gives the temperature at -12 degree and pressure at 320 kPa.

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...

@@SudhirBaujee You have a lot of houses! Good for you!

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. ua-cam.com/video/daYF4ksCBW4/v-deo.html

@@DrGucci thank you

You are energy professional?

"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.

Thank you very much sir 😊

Thank you buddy!

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. ua-cam.com/video/PqhjP2m6msc/v-deo.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 have not heard the term "guaranteed tensile strength" and "guaranteed tensile strain" so I do not know what they refer to. Sorry about that!
