You taught with lots of enthusiasm as usual

You my friend are a life saver. And very good at explaining all this. If this is for your PHd I wish you the best of luck.

Thanks Sirak. I completed my PhD in fluvial hydraulics and now searching for research position but couldn't get one. At least my videos you found useful, that's really motivating. I don't have much resources now, if i had a lab I could've done so much more in teaching hydraulics. But anyways, black board and chalk for now. All the best!

All the concepts regarding Choking & Unchoking of flow is cleared !! Thanks a lot sir 😌

A transition is constructed to connect two trapezoidal channels with bottom slopes of 0.001 and 0.0004, respectively. The channels have the same cross-sectional shape, with a bottom width of 3 m, a side slope of z = 2, and Manning's coefficient n = 0.02. The transition is 20 m long and is designed to carry a discharge of 20 m^3/sec. Assume an energy loss of 0.02 m is uniformly distributed through the transitional length. Determine the change in the bottom elevations at the two ends of the transition. CAN ANYONE SHARE THE SOLUTION TO THIS QUESTION PLEASE?

Thank you sir

Sir as you said "since E2 decresases so y2 would decrease, y2 is measured from hump and for that y2 would already be less than y1, then why do we say that water level line will come down and then say y2 is decreased. If water level line was straight after water hits hump still y2 is less than y1 coz it measured from hump top but why do we bring line down ?

Thanks so much you cover all with perfect explanation. Dear Sir, do you have lecture regards contraction transition solving if so please let me know the lecture number in your youtub channel with my best hope and pray for further successful.

[@abhijeet246]

Thank you so much ❤.. I couldn't find time to record that lecture.. But will try to upload it..

Do you have a video where you explain what happens when you change a direction of an open channel, maybe it makes a 90 degree turn?
