Mass and Energy balance on Evaporators

[@chintusharma7828]

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 🙏🙏🙏

[@kanchanvyas5490]

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

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!

[@gatecatalyst-deepakpandey3041]

Sure Ben ..I will

[@allenthomas4434]

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?

[@shaikh4023]

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

[@SanjayYadav-fy4dg]

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 ???

[@gatecatalyst-deepakpandey3041]

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👍

How to calculate heat transfer coefficient

[@alinedeboleto]

Hi, what books do you recommend on this subject?

[@gatecatalyst-deepakpandey3041]

Sorry for late reply ...for basics of balance on evaporators..unit operations by mccabe and Smith is sufficient.

Sir what is the price of the entire course of CH GATE on engenius app ?

[@gatecatalyst-deepakpandey3041]

Please contact 7974951500 for course details

[@raob6294]

what if the Tbp geatrer than Tf

[@gatecatalyst-deepakpandey3041]

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

sir please upload video on numerical problems of Net present worth (NPV) How to calculate NPV at start of operation and after 1 year.

Tf

[@diptibanduke5755]

in case of boiling point elevation , Tbp value should be changed in all equations, right? i mean in Cp(T-Tbp) also?

[@gatecatalyst-deepakpandey3041]
