Super Helpful, thank you very much! Will be checking out your other playlists as well

My teacher doesn’t teach this lesson so I’m browsing your lecture sir to understand it

[@learnacc]

total enthalpy = specific enthalpy x mass

Love you from Hk❤

Thank you so much 🥹🤍🤍🤍

[@gokayermis9867]

Hey, i have a question in my mind; why didn't we use our calculated spesific volume value while calculating the quality (at 07:53)? BTW great course, thx for everything Sir!

[@engineeringdeciphered]

I think that’s what I did? I used the specific volume that we calculated = vf + (x)vfg to solve for x

[@gokayermis9867]

@@engineeringdeciphered i mean why did we use value from table rather then 0.02m3/kg? Why didn’t our vf value become 0.02?

[@engineeringdeciphered]

The vf value is the specific volume of a saturated liquid, and ours is not a sat liq, ours is a mixture. So we plug in our v value as “v” and the sat liq value as “vf” and then vfg is vg - vf.
Does that make sense?

when i clicked the video i didnt expect to fully understand the solutions but wow i was wrong

[@KAManJunPoh]

hi dr, if the temperature and pressure of liquid-vapor mixture are provided together, which table A4 or A5 is more preferable for us to refer?

[@engineeringdeciphered]

You can do either! I like to go to A5 and the if my temperature is higher than the tsat for that pressure- then I know it’s superheated. Your other option is going to A4 and if your given pressure is lower than the psat for that temp- then you know it’s superheated. Either table should point you in the right direction!

Quality ratio of masses, not ratio of volume

[@ovokeraymond2436]

The v=0.02m3/kg is larger than vf. How is it between?

[@puseletsomatlala8485]

vf=0.0007435 m3/kg and vg=0.1229. The specific volume of the mixture is v=0.02m3/kg. So the specific volume of our liquid falls between the specific volume of a sat liquid (vf) and a sat vapor (vg). So in simpler terms vf< v
