I have seen many videos about the venturi meter and it's working but this is the best of all I got to understand in the first take. Moreover it's very clear and no need to memorize it again. Thank you for your efforts, keep posting so brilliantly.
❤Very good explanation, ma'am..... but I have a doubt. Why the length of divergent part should be more than that of convergent part? What of the length of convergent part and divergent part are same???
For clarity, you should show the actual dataset of pressure & velocity at each part in your system during steady state conditions (e.g. inlet pipe, along the converging conical part, center pipe, along the diverging conical part, outlet pipe). Showing the solved equation/s would also be useful.
It is because in diverging part, there are more chances of flow separation at the walls due to adverse presssure gradient and hence the diverging section needs to be made gradual sloping to avoid larger pressure losses. In the converging section, there is no chance of flow separation at the walls due to favourable pressure gradient and hence it can be made to slope steeply.
According to pascal law P=Force/unit Area Here increase in cross sectional from throat to divergent area value results decrease in pressure then how would u say that increase in pressure in diverging part
high velocity doesnt neccearly mean high pressure ,and velicoty is impossible to decrease pressure ,because ,what drops the pressure is a sudden drop in pipe structure ,not in presure ,a sudden change on the ongoing fluid which mostly vapor ,vapor means in the vapor phase ,not boiling phase ,but vapor ,thats why theh call it vapor pressure ,not boiling pressure
flow rate = K*Area of throat*sqrt(2*density*pressure diff.); where k=c/sqrt(1-(b^4)); c = discharge coefficient (0.99 for venturi meter, 0.75 for orifice plate; b = diameter of throat/diameter of inlet. K is also called flow coefficient
i think velocity is not what drips the pressure is created from the physical structure if the pipe ,and how gasses behave ,its similar to the expansion valve because its very similar ,because both systems qre dealibg with fluids and high pressure and low preseure ,i call it narrower locatoin ,vecause the physical structure of the piipe the allowed the pressure to drop ,not because velocity decreses pressure ,pressure is related to temp ,the higher the temp the higher ,why the higher because when gas is heated it needs more spqce to hold it but when you icreases it in a cylinder without heat sourve of coursr ,its always must be cold ,and here is the paradox ,because if u apply heat and pressure simlultaneously ,u can apply pressure and cold to a closed system ,thank you God ,or if u want colder ,u can start with co2 as a refregerant ,but a comoressor to commpress co2 must be strong without external intervention ,on default or factory settings ,the next cycle will be colder depending on what gas is found on the second refr unit because there is heqt exchange happens between the 2 systems and when this happens ,the 2 unit cold end could get u to 170

Concepts taught in this manner don't need to be memorized ever. Thanks for the efforts, much appreciated.
Thanks! this gave me visual explanation which is missing in indian education.
Great presentation and explanation. Awesome online learning and information.
Amazing explain
Great! Explain...Mam Please Explain with Mathematical Expressions and Questions asked in Exams...
madam excellent video.. with ur permission i wil use to show my students.. thanks..
Amazing, Very helpful, Thanks
Mechanical engineer top level 👏👏
Clear cut explanation 👌👌
Best video of venturimeter I have ever seen
we neeed more videos like this
Thank you ma'am 😊
❤Very good explanation, ma'am..... but I have a doubt. Why the length of divergent part should be more than that of convergent part? What of the length of convergent part and divergent part are same???
So that when fluid enter in the divergent part fluid flow walls se stick rahe
Mechanical engineer like karo
How is the preassure difference used to measure flow rate?
Pls aap industry me jo jo equipment use hote hai sabhi pr vedio banaye pump compressor heat exchanger reactor etc pls pls ❤
superb explanation
Excellent..
Thanks but why is Divergent longer than convergent part?
Thank you ma'am..
Most welcome
Thank you 👍👍👍
Keep going mam
Very nice
Superb awesome
great great

Thank you so much for your feedback
No need .... just us how to determine flow rate with the help of pressure diff obtained
Thanks.
TY!
good represent
Mam! Please Explain Differential Pressure Transmitter and U-tube Manometer
Good
Hi, how do I reduce the outlet pressure just so I can create a pressure differencd?
Madam please make a video on Instruments selection like Control valve ,flow meter etc
Awesome
why diverging part is longer than the converging part of venturimeter if it is doing same job to maintain pressure?
It is because in diverging part, there are more chances of flow separation at the walls due to adverse presssure gradient and hence the diverging section needs to be made gradual sloping to avoid larger pressure losses. In the converging section, there is no chance of flow separation at the walls due to favourable pressure gradient and hence it can be made to slope steeply.
@@harshitgupta4238 nice explain bro
Awsome
According to pascal law P=Force/unit Area
Here increase in cross sectional from throat to divergent area value results decrease in pressure then how would u say that increase in pressure in diverging part
Same doubt that how pressure decreases when area is also less
Nice☺
what is the formula in getting the pressure? because mine was wrong for using P=rho*g*Z
But the pressure at throat is lesser compared to convergent nozzle..then how come it would be same
nice explained but what is the angle of diversion part.
18degree bro
5-7°
Which software are you using to create this animations
pls reply
Microsoft power point
wow
where to get the dimensions of ventri, i need on e to create a cad model?
Google it

ur video is incomplete because how to calculate pressure in venturimeter not explain.
flow rate = K*Area of throat*sqrt(2*density*pressure diff.); where k=c/sqrt(1-(b^4)); c = discharge coefficient (0.99 for venturi meter, 0.75 for orifice plate; b = diameter of throat/diameter of inlet. K is also called flow coefficient
Why Venturi meter used vaccum???
👍👍👍👍
