See the free body diagram (at 2:25). I'm not sure what you mean. The weight of the water is the source of the downward force and the downward pressure on the gate. I hope that helps.
@@divyanshupratik826 That would be double counting the force F_v. The downward component of the hydrostatic pressure distribution on the gate (shown at 1:08) is caused by the weight of the semi-circle of water. So, I DID "consider an downward hydrostatic force due to depth h". That's why the pressure vectors (in red) get bigger with depth.
Sir I think centre of pressure should be taken from top becuz here 1.33m seems less than 1m in diagram at 8:38 2-0.6667 = 1.333 is lying below the centre

this type of videos are really helpful 🎉 currently studying for my first exam on Fluid Mechanics for CE. Thanks a lot !!!
Glad the hear the video was helpful. Good luck on the exam
Thank you! Very well presented. The clear explanations and graphics make it easy to understand.
Glad to hear that you found it helpful
Why haven't you considered F due to pressure (rho*g*h) downwards on the gate?

"1.33m seems less than 1m" doesn't make sense. Clarify and add a time stamp, if you have a real question.
Thanks OWO
