Fluid Mechanics - L3h- Pressure & its Measurement-Numericals on U-tube manometers

This video lecture is suitable for Diploma Students of Civil Engineering as well as for the aspirants who wish to brush up their basics.
Reference book: Fluid Mechanics by Birinder Singh (KAPSON Publication)
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

Mam why you stop uploading videos
Please upload videos more and more so we can make our concept clear

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 ??

[@civilengg.withakriti2556]

Yes it can be solved but needs simplification first.
Also, some old scientific calculators do not have the option to solve equations.

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

[@civilengg.withakriti2556]

13.6 is the specific gravity of mercury... Density of mercury = specific gravity of mercury x density of water

[@SapparlaSravanKumarNaidu]

Could u tell me it is in kg per meter square na how it is converted into newton per meter square

[@civilengg.withakriti2556]

Force = mass x Acc
Newton = kg x Acc due to gravity
Newton = kg x 9.81

[@sunny4483]

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

[@MS-qg1je]

Not able to understand the unit conversion of density

[@asdfghjk6478]

Can I ask you a few questions?

[@civilengg.withakriti2556]

Sure. Questions related to the topic being discussed in the video are welcome.

Patm ki bhi value hogi na

[@civilengg.withakriti2556]

We take Patm =0 in most cases.
If mentioned in the question then it's value is also considered

[@Motivexity.0]

26:24 why we choose 9.81

[@civilengg.withakriti2556]

The value of acceleration due to gravity is 9.81

Before solving problems please write the formula first

[@civilengg.withakriti2556]

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
