Particle released
The urea particles are released from the
porous inside wall.
Device requirements
•
The device should contain an
approximately 1 liter of liquid in the lower
boxwithout creating a large deformation.
•
The deformationand the pressures
developed while liquid is being inserted to
the lower chamber and air is being
inserted tobothupper chamberswill be
measured.
