15:00 Water hammer pressure wave generates from valve and travels upstream upto surgetank. Valve is located in powerhouse near turbine. So shouldn't 'L' in time period formula mean penstock length?
at 10:20,, there was only (H-hft) at denominator, but you put the value of net head is (H-hft-hfp), what is the correct one? the formula or the value? please
Hello sir... 😀 I was wondering if we have to design this surge tank in volume (m3): How do we consider the height of the tank, do we have to take difference between zmax and zdown or zup and zdown or is there other way to calculate it?
Can you solve this ? A power canal, bed width 15m, may be assumed to be rectangular in shape with a steady state of flow of 3m. The canal supplies water to power house three turbines, each turbine rated at a discharge of 30 m³/s. If the in the power house is suddenly thrown off so that two of the turbines have to be shut down, what would be the height of the surge in the canal.
your equation for determining (AS) is different with (Novak book)! if diamter of surge chamber is 6m, according to novak book As= 28.8 but according to your formula AS= 50 Why? and Zmax = 11.63 for Novak book and AS=28 but also by your formulas so different why?

After 11 months he did not answer yet your important question!!!!
Thank you so much for the clear explanation sir!

Great videos! Pls do some more videos abiut Hydropower, also could you do a video about calculation Catchment area using topographical map?
Thanks.
Sure

In substuting the value of (H-hft), you use net head(H-hft-htp); is it correct??? It's ok that the value you got is in safer side.
Yes

Formulae kisi code se liye hai ya book se?
Brother, RCC ko sabai course cover gareko jastai Hydropower ko pani Numerical sabai cover garidinu paryo IOE ko .
Ok i will try. 😊😊
Short and sweet 🥰
Thanks.
This method is similar for water pressurized pipeline?
I believe so
Hydropower ko whole syllabus cover hune gari numericals ko video banaunu paryo sir.
Ok
Can you make videos pf numerical on power and energy . And turbines
Ok I will make on it
Ok I will make on it
@@civilconst my exam of it is on next week. Please do that asap. Much appreciation thanks
@@civilconst plz plz make videos on topic power and
energy
what are the odds ?? lol
Can you give me reference of equations which you use ??
Defining null beam etabs
Thank you very much.
cheers
Can you please give the references where you took those equations?
Yes, i agree with that

@@civilconst I cant get this text book. is it accessible online
please upload design of side intech and trashrack please
Will try. Thanks
Primarily for water hammer..... :) penstock are already designed for water hammer
Thats what I said sir. for water hammer effect on water tunnel 😊😊
Hello, can you give me the reference?

hi there; could you introduce a matlab code for this system
Instead of writing theory directly tell ,otherwise good
Thanks for your suggestion
