No, this is a problem I'm trying to answer for a project. The geometry is not exactly as it is shown in the picture, i just made it to substantiate my explanation.
Homework Statement
An pillow is inflated with an pressure of let's say 20 hPa. Afterwards we place a weight of 10 Kg on the pillow, what is the pressure increase within the pillow?
P athmosthere = 1013 hPa
P cushion = 1013 + 20 = 1033 hPa
m = 10 Kg
g = 9.81 m/s^2
Amount of air in the pillow...
