what is the weight of atmospheric pressure on us

Answers

Answered by kvnmurty

1 atmospheric pressure is 1 * 10^5 Pa or N/m²

The area of our head/shoulders that is exposed to the pressure vertically is about
   = 50 cm * 10 cm + π * 6² cm² approximately
   = 0.06 meter²

Total force we experience on whole of our body due to 1 atm on top of us
   approximately = 1 * 10^5 * 0.06 = 6, 000 Newtons.

This is about 600 Kg weight. or force exerted by 600 kg stone for example.

kvnmurty: click on thank you

zoyastarfarooqi: what is this ??

zoyastarfarooqi: m in class 8 i dont know what u have written

kvnmurty: i have written that : air pressure is on our head. Surface area of our head is Pi * 6 cm square. The area of our shoulders, ponch and bums that are exposed to pressure can be around 500 cm^2. So total area = 0.06 m^2. these areas are approximate estimates.. Force on us is pressure * surface area.. The force is the weight and answer needed.
