Homework Statement
Balloon in vacuum, radius R0 = 5,0 cm, surface tension σ = 25 N/m.
a/ the pressure in the balloon p in,0 by radius R0………. pin,0 = ?
b/ relation to the pressure inside the balloon pin, depending on its radius R…?
c/relation to the pressure inside the balloon pin , depending on the pressure outside the balloon pout and on its radius R, surface tension is σ…….?
Homework Equations
a/ pin,0=4σ/R0 = 4.25/0,05 = 2kPa
b/ pin = 4σ/R
c/ pin = pout + 4σ/R
