A dynamic, dangerous and unseen application of fluid dynamics

[surajparida]

Overall papar doesn't depends on single question

[chinmay]

Meanwhile Ashish Arora Sir solved it in 2 minutes and said it was very easy question
God For a Reason 👑

[Abhay-bu]

Legends knowing this question is inspired from AH Shapiro "advanced fluid dynamics" aerospace engineering book.

Nightmare for aspirants ❌
Nightmare for teachers ✅

[SirPercy]

1. Density of hot air (ρ) inside furnace:
ρ = P / (R × T) where R = gas constant ≈ 287 J/kg·K for air
ρ ≈ 0.61 kg/m³ (using P = 101325 Pa, T = 360 K)

2. Velocity of hot air exiting chimney (v):
Apply Bernoulli's Equation between furnace and chimney exit:
P + 1/2ρv¹² + ρgy₁ = P + 1/2ρv²₂ + ρgy₂
Simplifying and neglecting pressure difference:
v₂ = √(2 × g × (y₂ - y₁)) = √(2 × 10 × 9) ≈ 13.42 m/s

3. Mass flow rate (m) of air exiting chimney:
m = ρ × A × v
where A = cross-sectional area of chimney = π × (d/2)² = π × (0.05)² ≈ 0.0079 m²
m ≈ 0.61 × 0.0079 × 13.42 ≈ 0.065 kg/s
m ≈ 65 g/s

Rounding to nearest integer:

m ≈ 65 (ans.) loo bhai hogaya kya hard tha isme 🎉

It is mentioned in Ah Shapiro engineering of advanced fluid dynamics

Rajkumar Sharma sir enters the chat 🌚🌚🌚

[kartikey-qtom]

And NEET kids says our physics is hard 🤡

[Jeeadv.o]

I think that jee advanced is very hard🥵🥶 but it is very easy...🤡🤡

[abhijitnath]

A single question don't decide the overall difficulty level of paper ... 2023 and 2024 paper was easy as compared to any other year's paper

[AliMohd-fi]

Only msm sir was able to give right answer

[shekharrajput]

My friend was the lowest to score in toppers list in NEET but was the only one to qualify in JEE ADVANCED
Any thoughts on this?

[RaviMehra-lejk]

KONSA Q CHODA HAI ✅

[deveshupadhyay]

Rotational motion 🥶🥶🥶🥶🥶🥶🥶🥶
The nightmare of every jee aspirants and all coaching teachers

[hackeryug]

Meanwhile the similar question was came in the MIT semester...🗿🗿🗿🗿🗿🗿🗿

[ayushchandra]

The question was so hard that even editor can't solve 😮😅
