Pressure is the force [tex]F[/tex] exerted by a gas, a liquid or a solid on a surface (or area) [tex]A[/tex], its unit is Pascal [tex]Pa[/tex] which is equal to [tex]N/m^{2}[/tex] and its formula is:
[tex]P=\frac{F}{A}[/tex] (1)
Now, we know the atmospheric pressure on Earth [tex]P_{E}[/tex] at sea level is:
[tex]P_{E}=101325 Pa[/tex] (2)
And we are told the atmospheric pressure at the surface of Venus [tex]P_{V}[/tex] is 91 times the pressure at sea level on earth:
[tex]P_{V}=91P_{E} [/tex] (3)
This means:
[tex]P_{V}=(91)(101325 Pa)[/tex] (4)
By solving equation (4) we will find the the atmospheric pressure at the surface of Venus:
[tex]P_{V}=922285 Pa[/tex] (5)
In order to find the force Venus's atmosphere would push on an average human being at sea level, we have to substitute the value of [tex]P_{V}[/tex] in equation (1) and find [tex]F[/tex] , assuming that the surface area of an average human being is [tex]1.8m^{2}[/tex]:
[tex]P_{V}=\frac{F}{A}[/tex]
[tex]F=(P_{V})(A)[/tex] (6)
[tex]F=(922285 Pa)(1.8m^{2})[/tex]
Finally:
[tex]F=1660113N[/tex]
