At sea level, the atmosphere exerts a pressure of 450 pounds on a surface with an area of 30 square inches. How much pressure per square inch does the atmosphere exert on surfaces at sea level?

Answer 1

#15p si#

The equation can be utilized.

#p = F_(⊥)/A#

where #p# is the pressure at the surface, #F_(⊥)# is the force perpendicular to the surface (commonly in newtons), and #A# is the area the force is acting upon, commonly is units of square meters.

Given the area (measured in square inches) and the force (measured in pounds), the pressure is

#p = (450lb)/(30i n^2) = color(blue)(15p si#
