Pressure (part 2) Atmospheric pressure…

βœ“ FINALLY DISCUSSING THAT BLA BLA😁

guys you have already learn about the topic atmospheric pressure in class 8th ( strange na, i know your face is like πŸ€”). So the scenario is, we are living under the pressure which is caused by our atmospheric gasses and thus pressure is called as atmospheric pressure (1atm). Guys believe me this is very large amount of pressure on our head then why not we are crushing under this pressure. Guys this question I’m leaving as it is for you allπŸ€“. Do comment in the comment box.

I know you are thinking about this bizzare image of little panda. Guys have you seen the cylindrical shape object on the head of panda filled up with gas particles, this is nothing but the volume of atmospheric air exerted on the head of panda or even every human being has loaded with this amount of gas on his/her head, so we are going to detailed it below😁 ….

We know 1atm = 10^5 Pa —-(approx). 1atm = 10^5. N/sq. m —(another unit of pascal)

It means force of 10^5 N is acting per metre sq. Then what should be the force acting per cm sq. Here is the calculation below :

so, we get in 1 atm pressure the force acting on one centimetre squared is 10N. Hence if the average area of a human head is 15Γ—15= 225 sq cm, the force acting on 225 sq cm is 2250 N.

Guys can you imaging this value of 2250 N. This aris almost 225 kg of load 😲 acting on our head and the fact is we are not crushing under this pressure.
