Correction 1:
The vacuum pressure in a manometer can be recognised if the level of Mercury in the right limb is lower than level of Mercury in the left limb.
By mistake in the video I have said lower than center of pipeline. Kindly note the correction.
Correction 2:
In the (b) part of Q4 the equation is
9810 + (-1.36+ 0.1- x + 27.2x) 9810 = 0
-1.26 + 26.2x + 1 = 0
-0.26 + 26.2x = 0
x = 9.92 x 10^(-3) m
Kindly go through the corrections mentioned in the description 🙏
Jis cheese ka need tha vo mil hi gya, mai aapko kaise dhnyawad bolu concept ek dum clear, no doubt.🥰
Thanks
M wlc mam...😊
Mam questions me to centre of pipeline se below Diya huaa hai na 0.18m
Tq so much mam it is very much useful
You're welcome... Stay tuned :)
Mam why you stop uploading videos
Please upload videos more and more so we can make our concept clear
Very very helpful thank you so much ❤
You’re welcome ☺️
Thanku you so much mam
You're welcome.... Stay tuned :)
Next day my exam of fluid mechanics and I'm watching your video at 8:00pm
All the best 😊
@@civilengg.withakriti2556 thank you maam ek question similar hi aaya tha 7 marks me, thank you very much ❤❤❤🔥
You’re welcome ☺️
Mam 70mm above the center of the pipe of murcury. Aaap niche kyun liye h. Uper hona chaiye sayad.q no2
Mam your voice is so beautiful.. ❤
Thanks 🙏🏽
Thank you ma'am
You're welcome 😊
Not able to understand the unit conversion of density
Aapke video Accha hai mam😊
Thank you
Could u tell me it is in kg per meter square na how it is converted into newton per meter square
Force = mass x Acc
Newton = kg x Acc due to gravity
Newton = kg x 9.81
bro elaborate clearly
if you askin about pressure then it's f/a in which force has unit of newton and area is in m²
Thank you so much mam🖤🖤
Most welcome 😊
Mam 13.6 is density of mercury or specific gravity of mercury........if that is density so why u again take water density just after taking 13.6 as mercury's density...........that's I don't understand.....plz reply
13.6 is the specific gravity of mercury... Density of mercury = specific gravity of mercury x density of water
Nice
Thank you
thank you ❤
You’re welcome
@@civilengg.withakriti2556 mam ab aap video kyun nhi upload karte hai
Mam jo last question me jo equation h
9810-(1.36+0.1-x +27.2x )9810=0
Ye calculator pr b ho skti h solve ??
Yes it can be solved but needs simplification first.
Also, some old scientific calculators do not have the option to solve equations.
Thanku ❤️ didi
You’re welcome
26:24 why we choose 9.81
The value of acceleration due to gravity is 9.81
Thank you maam
You're welcome 😊
Can I ask you a few questions?
Sure. Questions related to the topic being discussed in the video are welcome.
Thk u didi
🙏
Patm ki bhi value hogi na
We take Patm =0 in most cases.
If mentioned in the question then it's value is also considered
Mercury
I love you mam TQ
You're welcome 😊
Before solving problems please write the formula first
Please refer to the video where theory is being discussed where the formulae are discussed. Also, you’ll find the formulae written within the numerical problem as well
