m g /area
m = .050 KG
g = 9.8 m/s^2
area = pi r^2 = pi (9 *10^-6) meters^2
so
p = .0173 * 10^6 N/m^2 or Pascals
= 1.73 * 10^4 Pascals
or around .2 atmospheres
consider a vertical piston system. the piston has a 50g mass and a given radius of 3mm. what amount of pressure does the piston exert? ( use g==9.8 m/s^2 )
