The question at 02:26 has a mistake at the interpolation. a = 0.83844 where you stated a = 0.745 The answer for the specific volume is therefore 15.705 and not 15.612
Luckily you are not required to memorise the tables. They will be provided together with the exam paper (at least that is my experience). Just also ask your lecturer to confirm as I can’t speak on their behalf
@@AdriaanVanNiekerk yes why not.. Can you help us learn the numericals to know the pressure, quality, volume, enthalpy and internal energy in a single question? Like you need to make some table for it as well right..
You will be able to get all that properties from a table. You just need to know two properties for the state to be fixed. If you know two properties (for instance pressure and enthalpy) you will be able to get all the remaining properties
Where did you get the values for 5:08? They don't match the table shown, or the table that I use. I got 5.845206x10^-2 for quality (x)
Thanks for highlighting this. Your answer is correct. It seems like I took my values for specific volume at 10 kPa and not 100 kPa.

Hi Catja. You are correct, thank you for highlighting the error. The correct value for specific volume at 3:46 is 15.705 m^3/kg
You da homie thanks for the hw help
Thanks for the comment. I am glad the video was useful!
Are we supposed to memorize the table data or we can get them in exam paper?

@@AdriaanVanNiekerk okayy thankss
@@itsaddy4404 no problem. If you have any other thermodynamics related questions, send them my way 👍🏻
