Wow great video. Took 2 hours of reading the textbook and summed it up clearly in 15 mins. Another video with more challenging practice problems would be helpful. Thanks!
This is a great video specially for people who is taking Thermodynamic 1. The quality equation and linear interpolation equation will be used a lot including Fluid Dynamics class, Chemistry and Mechanics of Materials to name a few.
For the first example under Superheated pressure, we were given a value for pressure and a value for temperature. Do we need to find the saturation temperature using the value given for pressure? And if we do, what do we use the value of the saturation temperature for?
start with pressure based steam table. 1. look at the given pressure 2. in that line see the values of Specific internal energy. here you need to observe given value. from here you may see four cases. a) value of specific internal energy is equal to the value at saturated liquid state(e_f). here you can easily know all other quantities. b) value of specific internal energy is equal to the value at saturated vapor state(e_g). here also you can easily know all other quantities. c) if you see the value in between these two values that means it is in saturated mixture zone. using interpolation method you need to find dryness fraction first and later you can find all the quantities at this dryness fraction using interpolation. d) you may see the value specific internal energy greater than specific internal energy at vapor state. here you need to look at super heated steam table.
Thanks, But how about if Only Temperature and Enthalpy is only given then it is a superheated because the given enthalpy is greater than the sat. Enthalpy?
your temperature is fixed and you have value of enthalpy. look for your value of enthalpy in superheated steam table at various pressure at fixed temperature. select the closest value of enthalpy. if you dont find value closer than that then interpolate.
Since when is the volume of a tank expressed in m^3/kg?! Multiply the specific volume of the mixture by the total mass to yield the actual volume of the tank, or better yet, just use the individual masses of the liquid water and steam and multiply them by their respective specific volumes and sum them together. No need to use mass fractions here...
as per the data given in example, total mass is 10 kg and mass of vapor is 3 kg. dryness fraction or quality is ratio of mass of vapor to total mass. So , dryness fraction is 0.3 or quality is 30%.

Hands down its my first time to comment on a lecturing tutorial . Thanks alot for simplifying the work🎉
What will be the state of thermodynamic system in the following conditions:
1) vf
this video helped me to know how to interpolate in order to find values that are not stated on the table.
thanks a lot sir.
Dislike kon karke gaya yaar....pagal ho tum log....itna accha explain koi nahi karta.....btw thank you sir❤
The lecturer is very clear, explained with easy to unserstand examples.nicely and concisely presented. it is excellent
this is the best video on steam table available in RUclips,Thank you sir
just imagine...today is exam at 9, you started at 3, and majority questions come from a single 15 min video...😆
Thank you sir for providing such a great and easiest way of finding the parameters in steam table.
Great explanation. This will help a lot of people. Keep posting such informative videos. 👍
I completed my assignment from this single video, Thank you !
thanks for the video. do you have any more examples that i can practice?
Do you still need it?
Yes
@invisible voice
Very good at explaining. Thank you so much!!

Awesome explanation. Gudos 👍👍
Best explanation in a single video so far ! 🙇♥️
Thank you soo much for this video. You are a true life saver
Crystal clear explanation, thanks a lot!
EXCELLENT DESCRIBING
Thank you very much sir 🙌🏻🙌🏻🙌🏻🙌🏻
i love this lecture video. tq sir
The volume of the tank is given by V(volume)=m(mass)x v( specific volume) and is in cubic meters
its because he took specific volume in which we divide by mass so you can understand .
At 7:48 , if it asks for temperature 41°C then how can we approach??
Great piece of lectures
This helped tremendously! Thank you.
You are a God send Thank you too much
Explained well in an understandable way
Nicely explained sir
This was amazing! Thank you!
Well understood. Thank you
Also make video on problems on Rankin cycle, otto, diesel.... Numericals
Thank u sir.your way if teaching is excellent
THANK YOU SO MUCH! SUCH A LEGEND
At 7:48 , if it asks for temperature 41°C then how can we approach??
Sir thanks for the video mera kl bme ka paper hai or meri pht rhi thi lekin sir apki video dekhi to wapis sil gyi......Thanks😊
very helpful sir
Great video sir. Thanks a lot. It was very helpful 🙏🙏❤️
Very useful videos thank you
Thanks Dude. This is very well-explained.
So, dryness fraction is the synonim of steam quality (Oil field terminologi). Isn't it?
YES
Thanks sir ,i finally know how to interpolate
Great summary, will like to solve more complex questions
Great video!!
Good video! Easy to understand
How to distinguish that in the specific numerical which table to follow
عاشت أيدك حبي مقصرت والله احسن من دكتورة ابتسام هذيچ تخوط بصف الاستگان انتَ تخوط بالماعون
Good explanation
how did you do it can you share with me , thank you
Amazing video thank you
Best sir❤
Really helpful.....thank you sir
Hi there, what if the temperature was not 40 degree celcius but 43?
How to identify the delta H
Excellent explanation simple and clear.
Good
fantastic sir.. nicely explained
Thankyou so much👍👍👍
why do we need x for the calculation? we only have the fraction when encounter with volume?
For the first example under Superheated pressure, we were given a value for pressure and a value for temperature. Do we need to find the saturation temperature using the value given for pressure? And if we do, what do we use the value of the saturation temperature for?
Sir , at 5 bar steam pressure 1500 lit of water to raise the temp from 30 c to 90 c , how much steam in kJ is required ?
Thank You So much
V nice
please share your thermodynamic table of pur water with us !
Sir pls explain this using enthalphy
For supercooled liquid, what do we use?
Very nice explanation! Thank you so much

what if given temperature is 93.33C . HOW T PREDICT PROPERTIES THEN?
Wah
Thank you so much sir...it really helped me a lot
Super
thank you very much!
Thanks! Helped me a lot!
Superb
Thanks my man
Wonderful

How to know the other identities if Pressure and Specific internal energy is only given?
start with pressure based steam table.
1. look at the given pressure
2. in that line see the values of Specific internal energy. here you need to observe given value. from here you may see four cases.
a) value of specific internal energy is equal to the value at saturated liquid state(e_f). here you can easily know all other quantities.
b) value of specific internal energy is equal to the value at saturated vapor state(e_g). here also you can easily know all other quantities.
c) if you see the value in between these two values that means it is in saturated mixture zone. using interpolation method you need to find dryness fraction first and later you can find all the quantities at this dryness fraction using interpolation.
d) you may see the value specific internal energy greater than specific internal energy at vapor state. here you need to look at super heated steam table.
Thanks, But how about if Only Temperature and Enthalpy is only given then it is a superheated because the given enthalpy is greater than the sat. Enthalpy?
your temperature is fixed and you have value of enthalpy.
look for your value of enthalpy in superheated steam table at various pressure at fixed temperature. select the closest value of enthalpy.
if you dont find value closer than that then interpolate.
Thank you very much sir!/ma'am
Sir is it also applicable if temperature and entropy is given? Like in temperature and enthalpy?
Thanks sir
Since when is the volume of a tank expressed in m^3/kg?! Multiply the specific volume of the mixture by the total mass to yield the actual volume of the tank, or better yet, just use the individual masses of the liquid water and steam and multiply them by their respective specific volumes and sum them together.

There are many ways of solving a problem my friend
❤❤❤❤❤❤
👍🏻
thank u bro
Sir how is Vf/m+Vg/m=mfvf/m+mgvg/m
thankyou very mucho
Supper
why was 30% used?
as per the data given in example,
total mass is 10 kg and mass of vapor is 3 kg.
dryness fraction or quality is ratio of mass of vapor to total mass.
So , dryness fraction is 0.3 or quality is 30%.
if anybody have the steam table PDF can u please share it here. Thanks in advance
noice
