OMG thanks to your video I finally understand the Carnot Cycle for my presentation. Thank you so much !

In exam if you don't want to waste your time on writing long limitation. Then you write this much only , "But practically it is impossible to achieve" Therefore: "There is no real heat engine of 100% efficiency " 👆🏻This much is enough this contain that all things..🙂

[@vkgamer0155]

When we find the value of q 3 to 4 - it negative values then why not put the value of negative in efficiency of carnot ....??????

[@anirbanpandit680]

Exactly I'm saying

[@rajeshojha2642]

He is directly putting these values and this is an incomplete process

[@aryansharma3492]

No it's real formula is total work done /heat absorbed from the source . So , when we put the value of q 2-1 it's became negative . He is using direct method

1-2 isothermal expansion 2-3 adibatc expansion 3-4 isothermal compression 4-1 adibatc compression Isothermal meant change in T equals ZERO or T is constant throughout Adibatc means change in Entropy equals ZERO.

[@edutechguruengineeringlear4280]

kzbin.info/www/bejne/b5KuhZeYaNKMerc

[@kyrafromhere]

In adiabatic change in heat is zero right? How come change in entropy is zero

[@OmYash-z8w]

Because entropy equals transfer of heat by change in temperature

[@comewith_me6853]

In process 3-4 the workdone should be [-mRT2 ln(V3/V4) ]

[@debadityaghosh7612]

Yeah

[@leorailnfr]

Sir that part Q3-4 equals minus was there but after where the minus was out

[@PriyankaSharma-qh5lu]

Sir if adiabatic compression and adiabatic expansion is remove from carnot cycle than what happen and what is the efficiency

[@MLC-MARRI-YSRCP]

Nice hand. Writing and good explanation sir ..

[@rahuldhiman6607]

Process 1-2 is an isothermal process, how come T2 is then different from T1, constant temp expansion means there is no change in temp during the process, which according to your derivation implies that the efficiency is zero. And how this adiabatic process equation is applicable for the process 1-2

[@aswins7372]

No bro the temperature does not change in process 1-2.T1 is the constant temperature of process 1-2 and T2 is the constant temperature of the process 3-4 , so they are isothermal only

Where did the -ve sign go because heat produced by 4---1 was -ve And V4/V3 = V1/V2 then how can you cancel them by changing denominator with numerator (i.e V2/V1)

Thermodynamics gives you bounds on real engines. Moreover, the explosion of the fuel mixture is not even approximately reversible. How can thermodynamics be of any use, in designing real world internal combustion engines?

What happened to the -ve sign of Q3-4 when you substituted it in 1-(Q3-4/Q1-2)

[@goratagobuiwang6475]

Wasn't it supposed to be 1+T2/T1

[@ashishsaud6688]

@@goratagobuiwang6475 bro its cause Q3-4 is negative as compression i.e work done on the system is negative so the n = 1+ Q3-4/Q1-2 now n = 1 + T2ln(V4/V3)/T1ln(V2/V1) now after taking \-1 common we get n = 1- (T2/T1).

[@shivanipal8482]

Sir can you plz plz reply quickly my question answers 1. A piston cylinder system contained air is worked on carnot cycle to do some mechanical work. Initially ,the system contains air at 1bar ,298k and 0.01m3. the system is first compressed until the volume is 0.002m3 (isothermally) .after that, the system undergoes an expansion process (isothermally) to a point where pressure in the system is 5 bar .At that point , the system is subjected to an isothermal expansion process until system reaches the initial state completing a cycle. Calculate the net work done of the cycle and cycle efficiency.

[@Thinkdifferent998]

Carnot cycle is cyclic process? If it is then initial state should be equal to final state t1=t2, p1=p2 and so on. And plz explain reversible word you use in cycle? Is it means that you added hear from process 2 to 3 ,can reverse from 3 to 2 with out effecting system and surrounding In a cycle?

[@dikshantgarg7609]

NO BRO IN CHEMISTRY THERE IS A PROCESS I.E. REVERSIBLE IT IS A SLOW PROCESS THAT CAN MOVE BAVKWARD TO WND ATTAIN EQUILIBRIUM.
