Sir please also see Vinay Uppal Sir’s solution. His solution is also different from others. Unhone bahar hydrostatic condition nahi liya hai, but bernouli theorem lagayi hai also he used the concecpt of compressed fluids. Unhone concept ko poore deeply me jaakar solution diya. His answer is 47.1gm/sec. Also he didn’t ignore the height variation outside.

Sir upward direction me velocity badegi to density constant kaise rahegi.....

[@physicsgalaxyworld]

Yes that’s what sir is saying - in que it is clearly given that density is constant so velocity has to remain constant

Ma sir 🛐

[@letsevolve9441]

THANK YOU VERY MUCH FOR THE DETAILED EXPLANATION SIRJI❤ Also very grateful for every teacher who provided their soln with logics and discussion..

[@koq_utx]

Sir when I made a comment explaining NMS sir's solution. People started backfiring with how can you use kinematics in fluid 😂. I tried hard explaining them it is a specific analogy but people just blindly following the solutions which is marketed well enough and disrespecting other solutions.

[@koq_utx]

@anonymous sir galat is question ke situation par kaha hai. Like convection already start ho chuka hai us time par. NMS sir method is when convection hasn't started. But why his solution works is because tum khud socho convection start karne ke baad ek time esa aayega jab chimney me only hot air flow karegi and question wahi velocity mang raha hai. And tumne khud bola tha gas constant velocity se nikalti rahegi. So to sum it up, when convection hasn't started only cold air in chimney is present, then you start heating slowly initially hot gas has velocity zero then at some time only the hot gas will be remaining and the velocity will become constant. To NMS sir ne bas backtrack karke convection start hone ke time par velocity nikala using basic laws and aage to wahi velocity constant ho jaata hai na.

[@koq_utx]

@anonymous abhi samajh aaya pura story ? In simple words sometimes complex looking question uske intial condition se related hota hai so if you can figure that out isko hi deep thinking kaha hai ashish sir ne.

[@koq_utx]

@Anonymous1512-_- bhai bina matlab ki controversy hogi to IIT waale kyun hi pange lenge.

[@나강원-c6d]

According to the final answer key, both questions of the notorious chimney problem were dropped and marks would be granted to all students.

[@AdityaJee-us1pq]

the solutions of all teachers is correct. Only the initial assumptions make the difference.

[@167DanishSingh]

Sir its very clear in my mind that we can't use Bernoulli's equation inside the furnace ( but we can use Steady flow energy equation, but that too is useless in this case ) but why should it create a problem in applying Bernoulli's theorem outside the furnace ( within the H height ) ? (1) Applying Bernoulli within furnace & (2) Applying Bernoulli outside furnace _ why (1) & (2) are dependent on each other I still think we can't neglect the pressure change in the H height of column of air outside the furnace
