This video explains the energy balance on the evaporator and explains a numerical problem based on this Whatsapp@8076643294 mail: pandey.deepakiitr@gmail.com
Sir i have coverd 4-5 core subject from your recorded lectures for gate 2021 and got air 764 in first attempt. Thankyou sir, ur teaching style is awesome 🙏🙏🙏
Took me 1 month to find out your name and another month to finally find a dedicated channel of your videos .You teach really well Deepak Sir 😊. A GATE'21 aspirant
Hi Kanchan ...thank you so much for your dedication. I would like to tell you that I have started the course for GATE 2021 At engenius.in Also join this telegram group to stay updated t.me/joinchat/PKPEwxuAy8l6jALap1h0vw WhatsApp for any guidance 8076643294
Love your teaching style! Thank you so much for uploading this. Its helping alot for studying for my PE exam. Any chance you can do an example problem with given heat capacities instead of enthalpy values? It would be greatly appreciated!
Sir why we have taken enthalpy of product HV=0 (is always TBPin=TBPout) in the energy balance. What is the general product temp is it always equal to the temp inside the Evaporator
Deepak sir, can we take atm temp.as a refrence temp, in that case we have to include product energy also but sir I am confused with vapor energy , so what wiill be vapour energy in case of atm reference temp. Can you write the energy balance with atm reference temp ???
While choosing reference, two things need to be considered Reference temperature Reference state If I choose liquid state and 25 degree as reference, then the enthalpy of liquid at 25 degrees is zero but if vapour is present at 25 degrees it's enthalpy is non zero since reference state is liquid .. Hope I was able to clear your confusion👍
Sir, but Tbp is higher than Tf right? Coz one is boiling point of solution, and other is Feed Temp. And where does the V.Hv term go in the mass balance? Though it's getting evaporated it's got some mass right?
If Tbp is taken as reference , then still you have to write Tf - Tbp. Of course the enthalpy will be negative , but that is not going to do any harm to your calculations. Enthalpy is a relative quantity, so can be negative as well
You can access the complete process calculations. Lectures at engenius.in We are offering the subjectiwise as well as complete course for chemical engineering....thanks for watching

More much knowledge for chemical engineer in this channel thanks sir❤
Yur teaching style is just amazing sr, very good
Thank you ankish
Thank u soo muchh sir .First tym I got cleared about evaporater.
Welcome dear. ..
My complete course on GATE 2021 is available at engenius.in . Visit the portal for more details

Sure Ben ..I will
Always the best teacher
Thank you so much dipesh...
Thank you so much sir! Helped me alot
Thank you Shilpa ...complete course for Gate CH is available on engenius app
Pls upload more video of EB/ MB numerical
Tf
thanks sir
sir please upload video on numerical problems of Net present worth (NPV)
How to calculate NPV at start of operation and after 1 year.
What you are asking is a particular problem ...you can ping me on WhatsApp for your doubt ...it will not take much time
@@gatecatalyst-deepakpandey3041 ok sir
Thanks a lot.
Sir why we have taken enthalpy of product HV=0 (is always TBPin=TBPout)
in the energy balance.

@@gatecatalyst-deepakpandey3041 sir please write energy balance equation with assuming any reference temp or existing temp of individual streams
Sir, but Tbp is higher than Tf right?
Coz one is boiling point of solution, and other is Feed Temp.
And where does the V.Hv term go in the mass balance?
Though it's getting evaporated it's got some mass right?
Sir,please make video on energy balance for recovery system in a column,please🙏
Thnku sr
what if the Tbp geatrer than Tf
If Tbp is taken as reference , then still you have to write Tf - Tbp. Of course the enthalpy will be negative , but that is not going to do any harm to your calculations. Enthalpy is a relative quantity, so can be negative as well
in case of boiling point elevation , Tbp value should be changed in all equations, right? i mean in Cp(T-Tbp) also?
Deepti you are right ..thanks for watching the videos ...stay connected at 8076643294 for other queries related to GATE CHEMICAL ENGINEERING
How to calculate heat transfer coefficient
Hi, what books do you recommend on this subject?
Sorry for late reply ...for basics of balance on evaporators..unit operations by mccabe and Smith is sufficient.
@@gatecatalyst-deepakpandey3041 Thank you so much!
Sir what is the price of the entire course of CH GATE on engenius app ?
