Air pressure

The meteorological station measured the air pressure of 1060 hPa (hectopascals). In addition to measuring instruments, there is a residential house that has a flat roof with dimensions of 10 m and 28 m. What pressure force in MN (meganewtons) force the air on this roof?

Correct result:

x =  29.68 MN

Solution:

a=10 m b=28 m S=a b=10 28=280 m2 p=1060 hPa p2=p/10/1000=1060/10/1000=53500=0.106 MPa x=p2 S=0.106 280=74225=74225 MN=29.68 MN
