51MILESAIR (Hydrostatic pressure)

Hello everyone , Well this blog is about how everything around us makes sense when seen in the way they are supposed to be....One thing that we always take for granted are natural resources and we do not realize how big impact they make in keeping things balanced .....Oh wait a second this is deviating right ,let me put it straight with an example, assume that two people(Buzzz &Woodyy) Buzzz in a pool standing 34 feet deep and woodyy in his lawn with 269280 feet atmospheric air on him.............Who would feel the most pressure ?

Well you are mistaken if you take sides

🙃...........

They both experience the same pressure on their respective bodies, Here is why "HYDROSTATIC PRESSURE" It is the pressure exerted by a fluid in rest, and it is obvious that most of us would have fallen for the big number 269280 feet , it would have been correct if woody is not surrounded by air, In the case of buzz the water surrounding him is at a depth of 34 feet a relatively smaller number compared to 269280 so there's something else that makes the cast of "TOY STORY" experience the same pressure ..........

What would it be???

Hint: It's not "bo -peep"

It's density(rho) ........So summing up all the drama it is evident that the hydrostatic pressure is the one that depends on height , density and obviously gravity.........

Presenting you the bad a** formula

which can make or break fluid statics

P=rho*g*h

h=height

g=gravity

rho=density

Lets talk numbers now

We ourselves are under a pressure created by atmospheric air which is 1atm(refer units of pressure) substituting g=10 m/sec^2 and p=1atm you get 269280 feet which is 51milesair.........and similarly for water substituting height =10.33m or 34 feet we end up getting 1atm.So now you Know why that buzz and woody are under same pressure ....😁😁

Stuff helpful for engineers

When you design a pump there's one thing that haunts you which is Cavitation which can be avoided by maintaining net positive suction head......which can be done by increasing the height of the suction line thus increasing the pressure on the suction side.....My later blogs will cover NPSH.......

Note that buzz is under a pressure of 2atm if absolute is considered...i sticked with gauge..don't get confused👍🤟
