Hi,
Anyone here took the PW super 1500 batch for GATE 2026 or before, how was your experience is it worth joining? Basically we have to dedicate time to that so thinking about it whether it is really value added to our preparation or not. Appreciate ur help!
Thanks.
I’m trying to understand the derivation from Navier–Stokes → Euler → Bernoulli. My confusion is about where the incompressibility assumption enters.
I start with the incompressible Navier–Stokes equation. After assuming inviscid flow, I get Euler’s equation. Then, taking the equation along a streamline and integrating gives the Bernoulli equation.
But I’ve also seen a more general Bernoulli equation for compressible flow(last equation in image). If I started from the incompressible Navier–Stokes equation, where density is already assumed constant, how can the derivation lead to the compressible form?
Also, is the differential equation along a streamline valid for both compressible and incompressible flow, with the difference appearing only when we integrate it?
Hi,
I am a student, attending long hours(7+ hours daily) on online lectures. I have a boat wired earphones, I'm currently using them, from the past few days I'm experiencing ear pain and feeling itching inside the ear. And when the device is in full volume sound is coming out loud anyone within 1m distance can hear the small sound coming from the earphones.
I need the best recommended wired in-ear type-c earphones. Please take a min and recommend some good earphones.
Thanks!
Hi,
These 18 fundamental hand motion symbols are used in work study and measurement in industries for proper utilisation of machinery and manpower.
Have any of you guys ever used these symbols in the industry?
Hello all,
Anyone draws a shear stress plot for the same, I have shown a linear velocity profile
Velocity gradient in y direction is constant for both the fluids but its magnitude will be different for both and at interface shear stress is the same for both, anyone show how to draw shear stress plot for the same.
Thank you

Hi guys,
Congratulations all the people who got some good ranks/scores selected in psus and iits, can guys suggest a safe rank to get into psu I cannot afford doing mtech, not financially good rn. Preparing for the gate to appear in 2027. I'm from the obcncl category.
Anyone based on ur exp and knowledge help will be appreciated.
Thanks 🙏
Can any one explain what are the approximate Solutions of tanx = x?
Thanks.
