Sir To be honest ..it doesn't look like 70 Ltr per sec discharge....water has to travel 14 feet per sec through that 15 cm pipe....doesn't look it's travelling at that speed.....or maybe I can't see in the video clearly.....
I thank you for sharing your view about this trajectory method. As for my opinion, pipe angle will affect if Y value is not taken accurately. I meant, the Y length will be taken up to vina-contracta.
We did all these experiments including v-notch method in Fluid mechanics lab... Civil engineering.... But didn't know it could be applied for borwell too
The formula and procedure for discharge measurement through trajectory method would be same only we will convert l/ sec into m3/sec by multiplying the multiplication factor that is 3.6, we will get the discharge in m3/hr.
Thanks a lot sir... Sir, I've a question... How dam discharge is found?... As it is of huge size to measure these quantities... Hope you'll reply soon... Loved ur this video😍😍😊👌
I thank you for your query. Power and discharge both are not similar. Suction and delivery of pump plays more important role in discharge. Larger the dia of inflow (suction) and outflow of pump will deliver higher discharge. HP is power required to deliver the discharge.
@@watermanagement1808 Thank you. Sir, can I use the flow rate of 70.565 l/s using 150 mm pipe for my project ? If not, Can you please guide me what is the velocity I should assume for 150 mm pipe to get the flow rate.
Dear Sir, it’s been a while I have been watching your videos. I have question regarding trajectory method. In the formula you used 0.0174 for calculating discharge. I want to know from where does it came from? Thanks.
@@watermanagement1808 Thanks for getting back to me. I have performed this exercise to get the draft calculations in irrigation sector and we used to calculate discharge in GPM. The formulae used was :- 3*Area*X coordinate √9 (3*A*X √9) where y coordinate is kept constant I.e 9 inches. Do you think the value (3) used in this formula is also taken as a coefficient?
Sir please pressurized irrigation ky bary main bnain detail main.. How we calculae motor horse power Design of drip and sprinkler by software Pressure requirements etc..
1 Cusec is equal to 28.32 lips When we divide lps by 28.32 we will get the value in cusecs. Now take an example of calculated discharge, that is 70.565 lps.. The cusecs will be 2.49.
It is concepts of horizontal projectile......bhaisaab ye formula tabhi sahi hai jab tubewell jameen se ekdum parallal ho Aapka answer theek hai ..... Wse iska exact answer 70.542556 l/s hai.....
X is the horizontal distance measured from the end of the pipe to the end of flow along the flow direction. Y is the vertical distance from the end of the flow vertically down on the surface of jet along Y Axis. Jet of water is flow of water passing through the crossection of pipe in round shape.

Good day sir, how can we measure the Y or the vertical from where?
Thank you
Teşekkürler
Great sir; Thank You! Very useful for on-site discharge measurement.
Amazing brother❤
how to know wether that disharge valu is in sec or what
great work dear
accuracy may vary as pipe angle varies trajectory also varies....
I thank you for sharing your view about this trajectory method.

Good work. Good effort to spread knowledge. Keep it up please 🙏
How to measure discharge when water flow varticaly
We did all these experiments including v-notch method in Fluid mechanics lab... Civil engineering.... But didn't know it could be applied for borwell too
Yes this is true. We can apply this method to measure the discharge of tube well too.
Thanks sir
Thank you sir
Thanks sir i am also studying in fae tandojam
If we keep y constant i.e y=12" or 6". so what will be the formula for Q in case m3/h
The formula and procedure for discharge measurement through trajectory method would be same only we will convert l/ sec into m3/sec by multiplying the multiplication factor that is 3.6, we will get the discharge in m3/hr.
incase of y value is o.so what will do
Thanks a lot sir... Sir, I've a question... How dam discharge is found?... As it is of huge size to measure these quantities... Hope you'll reply soon... Loved ur this video😍😍😊👌
This mathod is for pipe and if u want discharge from dam then you know from gate opening height
Plz sir gee briefly explain krya how the find discharge dam and Barrage
Thank you sir, just one doubt.... If we install a pump of higher HP, then the discharge will more right ?
I thank you for your query.
Power and discharge both are not similar.
Suction and delivery of pump plays more important role in discharge. Larger the dia of inflow (suction) and outflow of pump will deliver higher discharge.
HP is power required to deliver the discharge.
@@watermanagement1808 Thank you. Sir, can I use the flow rate of 70.565 l/s using 150 mm pipe for my project ? If not, Can you please guide me what is the velocity I should assume for 150 mm pipe to get the flow rate.
The safe velocity in pipes (of any diameter) should be less than 5 ft/sec or 1.5m/ sec.
@@watermanagement1808 Thanks sir 👏
Dear Sir, it’s been a while I have been watching your videos. I have question regarding trajectory method. In the formula you used 0.0174 for calculating discharge. I want to know from where does it came from? Thanks.
Hi, the figure 0.0174 is a coefficient used in this formula for calculating discharge through Trajectory method.
@@watermanagement1808 Thanks for getting back to me. I have performed this exercise to get the draft calculations in irrigation sector and we used to calculate discharge in GPM. The formulae used was :- 3*Area*X coordinate √9 (3*A*X √9) where y coordinate is kept constant I.e 9 inches. Do you think the value (3) used in this formula is also taken as a coefficient?
Hi,
Can you give a reference of this formula? I have searched a lot but didn't found solid reference for this equation
From where we should measure the height i.e. y ?
It's your wish..... Just note both the x(horizontal) and y(vertical) value....better consider x at a certain distance away from the pipe
Very good information for farmers thanks
I thank you for your comment.
sir( Q =0.174 * d square *x)/ Root y. please tell me for the value of 0.174
This value is constant
Unit of discharge is cusec or cumec
Here in this calculation, the unit will be LPS. After you can concert it in cusec or in cumec
Sir please pressurized irrigation ky bary main bnain detail main..
How we calculae motor horse power
Design of drip and sprinkler by software

Hello sir how to convert cm measurements into L/S
Actually CM is the linear measurement or we can say it is one dimenssinal and Litter is volume measuremt.
sir answer is in L/sec, how it will convrrt into cusec or cumes.?
1 Cusec is equal to 28.32 lips
When we divide lps by 28.32 we will get the value in cusecs.
Now take an example of calculated discharge, that is 70.565 lps.. The cusecs will be 2.49.
Sir v- notch se borewell ka water dicharge kese find krte h
Well expained
Bhai RK BANSAL book follow Karo page no 338 concept almost clear ho jaega....
How 154 comes here ??
Are yar.. Horizontal distance consider kiye hai.... 1540mm or 154 cm so don't confuse.....
जो आपने समझाया आप खुद वीडियो चालू करके देखो अपनी जो समझाया वह समझ में आता है
Is that pipe really giving 70lits per sec
Yes, the pipe diameter is 6" (15 cm). As the pipe is flowing full and as per calculation it gives such flow.
I think in one second even a bucket of 20litres will not be filled...sir can you make a video where we can check with a bucket or balti...
70 liter /sec is it true answer,pls check again
It is concepts of horizontal projectile......bhaisaab ye formula tabhi sahi hai jab tubewell jameen se ekdum parallal ho
Aapka answer theek hai ..... Wse iska exact answer 70.542556 l/s hai.....
its a good information
How to measure x and y Distance please sir explain in breef and also tell about what is jet of water?
X is the horizontal distance measured from the end of the pipe to the end of flow along the flow direction.
Y is the vertical distance from the end of the flow vertically down on the surface of jet along Y Axis.
Jet of water is flow of water passing through the crossection of pipe in round shape.
I would suggest to watch the Part 2 video. I would love to answer your questions.
Sir how can you get 0.0017 in formula
Please explain sir
Ye factor hota h isme jaha liter m dishcharge
Measurement of y is not appearing in video
Good information
But how 154?
I thank you for you valuable comment.
I will prepare another video, wherein all quarries will be answered.

Sir Hindi Mein video bnaayi plz or Kiya mm m le skte
Hi Mukesh, I am sorry I couldn't understand your message. Could you write it in English.
Discharge =70.49 L /s
Nice sir from which place you are???
Thank you. I am from Hyderabad.
@@watermanagement1808 keep on making such informative videos
Y value is assumed
Formula please
Please watch my complete video. You will find formula and its application.

Good Question.
For earthen Watercourses, the discharge will be measured through Flumes. Mostly we use Cutthroat Flume.
@@watermanagement1808 sir or bhi video bnain
Sure. Soon
@@watermanagement1808 sir agar flume na ho to kiya kren
If you don't have Cutthroat flume, then you would have to use Float method.
y ki valu kaha se aai
Y distance actually perpendicular from top of water surface.... To top of water surface film
